Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100478, here are decompositions:
- 19 + 100459 = 100478
- 31 + 100447 = 100478
- 61 + 100417 = 100478
- 67 + 100411 = 100478
- 181 + 100297 = 100478
- 199 + 100279 = 100478
- 211 + 100267 = 100478
- 241 + 100237 = 100478
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 100,478 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 100478 first appears in π at position 196,064 of the decimal expansion (the 196,064ordinal-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.
