Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100878, here are decompositions:
- 31 + 100847 = 100878
- 67 + 100811 = 100878
- 79 + 100799 = 100878
- 109 + 100769 = 100878
- 131 + 100747 = 100878
- 137 + 100741 = 100878
- 179 + 100699 = 100878
- 229 + 100649 = 100878
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 100,878 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 100878 first appears in π at position 383,114 of the decimal expansion (the 383,114ordinal-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.
