Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545402, here are decompositions:
- 11 + 31545391 = 31545402
- 23 + 31545379 = 31545402
- 29 + 31545373 = 31545402
- 59 + 31545343 = 31545402
- 71 + 31545331 = 31545402
- 73 + 31545329 = 31545402
- 79 + 31545323 = 31545402
- 103 + 31545299 = 31545402
Showing the first eight; more decompositions exist.
