Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603680, here are decompositions:
- 23 + 31603657 = 31603680
- 37 + 31603643 = 31603680
- 67 + 31603613 = 31603680
- 71 + 31603609 = 31603680
- 103 + 31603577 = 31603680
- 113 + 31603567 = 31603680
- 127 + 31603553 = 31603680
- 191 + 31603489 = 31603680
Showing the first eight; more decompositions exist.
