Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100978, here are decompositions:
- 41 + 100937 = 100978
- 47 + 100931 = 100978
- 71 + 100907 = 100978
- 131 + 100847 = 100978
- 149 + 100829 = 100978
- 167 + 100811 = 100978
- 179 + 100799 = 100978
- 191 + 100787 = 100978
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 100,978 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 100978 first appears in π at position 196,590 of the decimal expansion (the 196,590ordinal-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.
