Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535936, here are decompositions:
- 109 + 31535827 = 31535936
- 127 + 31535809 = 31535936
- 139 + 31535797 = 31535936
- 433 + 31535503 = 31535936
- 673 + 31535263 = 31535936
- 709 + 31535227 = 31535936
- 823 + 31535113 = 31535936
- 829 + 31535107 = 31535936
Showing the first eight; more decompositions exist.
