Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535880, here are decompositions:
- 53 + 31535827 = 31535880
- 59 + 31535821 = 31535880
- 71 + 31535809 = 31535880
- 83 + 31535797 = 31535880
- 127 + 31535753 = 31535880
- 139 + 31535741 = 31535880
- 163 + 31535717 = 31535880
- 199 + 31535681 = 31535880
Showing the first eight; more decompositions exist.
