Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684378, here are decompositions:
- 19 + 8684359 = 8684378
- 37 + 8684341 = 8684378
- 271 + 8684107 = 8684378
- 331 + 8684047 = 8684378
- 349 + 8684029 = 8684378
- 691 + 8683687 = 8684378
- 739 + 8683639 = 8684378
- 919 + 8683459 = 8684378
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 8,684,378 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
