Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535856, here are decompositions:
- 29 + 31535827 = 31535856
- 47 + 31535809 = 31535856
- 59 + 31535797 = 31535856
- 103 + 31535753 = 31535856
- 109 + 31535747 = 31535856
- 139 + 31535717 = 31535856
- 199 + 31535657 = 31535856
- 223 + 31535633 = 31535856
Showing the first eight; more decompositions exist.
