Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535680, here are decompositions:
- 23 + 31535657 = 31535680
- 41 + 31535639 = 31535680
- 47 + 31535633 = 31535680
- 89 + 31535591 = 31535680
- 131 + 31535549 = 31535680
- 251 + 31535429 = 31535680
- 257 + 31535423 = 31535680
- 263 + 31535417 = 31535680
Showing the first eight; more decompositions exist.
