Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990148, here are decompositions:

  • 11 + 990137 = 990148
  • 149 + 989999 = 990148
  • 167 + 989981 = 990148
  • 197 + 989951 = 990148
  • 227 + 989921 = 990148
  • 239 + 989909 = 990148
  • 311 + 989837 = 990148
  • 317 + 989831 = 990148

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 990,148 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 990148 first appears in π at position 506,621 of the decimal expansion (the 506,621ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
