Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612646, here are decompositions:
- 19 + 31612627 = 31612646
- 73 + 31612573 = 31612646
- 193 + 31612453 = 31612646
- 223 + 31612423 = 31612646
- 277 + 31612369 = 31612646
- 283 + 31612363 = 31612646
- 337 + 31612309 = 31612646
- 577 + 31612069 = 31612646
Showing the first eight; more decompositions exist.
