Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539392, here are decompositions:
- 43 + 31539349 = 31539392
- 61 + 31539331 = 31539392
- 103 + 31539289 = 31539392
- 109 + 31539283 = 31539392
- 151 + 31539241 = 31539392
- 163 + 31539229 = 31539392
- 229 + 31539163 = 31539392
- 331 + 31539061 = 31539392
Showing the first eight; more decompositions exist.
