Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535184, here are decompositions:
- 11 + 31535173 = 31535184
- 13 + 31535171 = 31535184
- 41 + 31535143 = 31535184
- 53 + 31535131 = 31535184
- 61 + 31535123 = 31535184
- 71 + 31535113 = 31535184
- 101 + 31535083 = 31535184
- 103 + 31535081 = 31535184
Showing the first eight; more decompositions exist.
