Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100312, here are decompositions:
- 41 + 100271 = 100312
- 263 + 100049 = 100312
- 269 + 100043 = 100312
- 293 + 100019 = 100312
- 383 + 99929 = 100312
- 389 + 99923 = 100312
- 431 + 99881 = 100312
- 479 + 99833 = 100312
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,312 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100312 first appears in π at position 627,078 of the decimal expansion (the 627,078ordinal-suffix:th 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.
