Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621632, here are decompositions:
- 11 + 31621621 = 31621632
- 19 + 31621613 = 31621632
- 41 + 31621591 = 31621632
- 71 + 31621561 = 31621632
- 73 + 31621559 = 31621632
- 101 + 31621531 = 31621632
- 131 + 31621501 = 31621632
- 191 + 31621441 = 31621632
Showing the first eight; more decompositions exist.
