Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535640, here are decompositions:
- 7 + 31535633 = 31535640
- 47 + 31535593 = 31535640
- 89 + 31535551 = 31535640
- 137 + 31535503 = 31535640
- 173 + 31535467 = 31535640
- 211 + 31535429 = 31535640
- 223 + 31535417 = 31535640
- 229 + 31535411 = 31535640
Showing the first eight; more decompositions exist.
