Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100784, here are decompositions:
- 37 + 100747 = 100784
- 43 + 100741 = 100784
- 163 + 100621 = 100784
- 193 + 100591 = 100784
- 283 + 100501 = 100784
- 337 + 100447 = 100784
- 367 + 100417 = 100784
- 373 + 100411 = 100784
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 100,784 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 100784 first appears in π at position 261,040 of the decimal expansion (the 261,040ordinal-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.
