Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535568, here are decompositions:
- 17 + 31535551 = 31535568
- 19 + 31535549 = 31535568
- 101 + 31535467 = 31535568
- 139 + 31535429 = 31535568
- 149 + 31535419 = 31535568
- 151 + 31535417 = 31535568
- 157 + 31535411 = 31535568
- 191 + 31535377 = 31535568
Showing the first eight; more decompositions exist.
