Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984978, here are decompositions:
- 19 + 984959 = 984978
- 31 + 984947 = 984978
- 47 + 984931 = 984978
- 61 + 984917 = 984978
- 67 + 984911 = 984978
- 97 + 984881 = 984978
- 101 + 984877 = 984978
- 131 + 984847 = 984978
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 984,978 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 984978 first appears in π at position 151,072 of the decimal expansion (the 151,072ordinal-suffix:nd 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.
