Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538064, here are decompositions:
- 11 + 31538053 = 31538064
- 17 + 31538047 = 31538064
- 31 + 31538033 = 31538064
- 67 + 31537997 = 31538064
- 83 + 31537981 = 31538064
- 193 + 31537871 = 31538064
- 227 + 31537837 = 31538064
- 241 + 31537823 = 31538064
Showing the first eight; more decompositions exist.
