Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545438, here are decompositions:
- 31 + 31545407 = 31545438
- 37 + 31545401 = 31545438
- 47 + 31545391 = 31545438
- 59 + 31545379 = 31545438
- 107 + 31545331 = 31545438
- 109 + 31545329 = 31545438
- 139 + 31545299 = 31545438
- 151 + 31545287 = 31545438
Showing the first eight; more decompositions exist.
