Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540194, here are decompositions:
- 5 + 31540189 = 31540194
- 13 + 31540181 = 31540194
- 31 + 31540163 = 31540194
- 47 + 31540147 = 31540194
- 71 + 31540123 = 31540194
- 131 + 31540063 = 31540194
- 163 + 31540031 = 31540194
- 181 + 31540013 = 31540194
Showing the first eight; more decompositions exist.
