Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481208, here are decompositions:

  • 31 + 481177 = 481208
  • 37 + 481171 = 481208
  • 61 + 481147 = 481208
  • 67 + 481141 = 481208
  • 157 + 481051 = 481208
  • 199 + 481009 = 481208
  • 229 + 480979 = 481208
  • 241 + 480967 = 481208

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 481,208 and was likely granted around 1892.

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

Position in π

The digit sequence 481208 first appears in π at position 560,892 of the decimal expansion (the 560,892ordinal-suffix:nd 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.
