Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998430, here are decompositions:

  • 7 + 998423 = 998430
  • 11 + 998419 = 998430
  • 19 + 998411 = 998430
  • 31 + 998399 = 998430
  • 53 + 998377 = 998430
  • 101 + 998329 = 998430
  • 149 + 998281 = 998430
  • 157 + 998273 = 998430

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 998,430 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 998430 first appears in π at position 560,271 of the decimal expansion (the 560,271ordinal-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.
