Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540848, here are decompositions:
- 11 + 31540837 = 31540848
- 61 + 31540787 = 31540848
- 139 + 31540709 = 31540848
- 149 + 31540699 = 31540848
- 179 + 31540669 = 31540848
- 191 + 31540657 = 31540848
- 197 + 31540651 = 31540848
- 211 + 31540637 = 31540848
Showing the first eight; more decompositions exist.
