Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104978, here are decompositions:
- 7 + 104971 = 104978
- 19 + 104959 = 104978
- 31 + 104947 = 104978
- 61 + 104917 = 104978
- 67 + 104911 = 104978
- 109 + 104869 = 104978
- 127 + 104851 = 104978
- 151 + 104827 = 104978
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 104,978 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 104978 first appears in π at position 76,371 of the decimal expansion (the 76,371ordinal-suffix:st 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.
