Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492694, here are decompositions:
- 3 + 31492691 = 31492694
- 31 + 31492663 = 31492694
- 43 + 31492651 = 31492694
- 67 + 31492627 = 31492694
- 97 + 31492597 = 31492694
- 127 + 31492567 = 31492694
- 157 + 31492537 = 31492694
- 223 + 31492471 = 31492694
Showing the first eight; more decompositions exist.
