Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100812, here are decompositions:
- 11 + 100801 = 100812
- 13 + 100799 = 100812
- 43 + 100769 = 100812
- 71 + 100741 = 100812
- 79 + 100733 = 100812
- 109 + 100703 = 100812
- 113 + 100699 = 100812
- 139 + 100673 = 100812
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 100,812 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 100812 first appears in π at position 723,572 of the decimal expansion (the 723,572ordinal-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.
