Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533600, here are decompositions:
- 13 + 31533587 = 31533600
- 19 + 31533581 = 31533600
- 29 + 31533571 = 31533600
- 37 + 31533563 = 31533600
- 53 + 31533547 = 31533600
- 67 + 31533533 = 31533600
- 83 + 31533517 = 31533600
- 89 + 31533511 = 31533600
Showing the first eight; more decompositions exist.
