Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100378, here are decompositions:
- 17 + 100361 = 100378
- 107 + 100271 = 100378
- 227 + 100151 = 100378
- 269 + 100109 = 100378
- 359 + 100019 = 100378
- 389 + 99989 = 100378
- 449 + 99929 = 100378
- 569 + 99809 = 100378
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 100,378 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 100378 first appears in π at position 769,090 of the decimal expansion (the 769,090ordinal-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.
