Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545468, here are decompositions:
- 29 + 31545439 = 31545468
- 61 + 31545407 = 31545468
- 67 + 31545401 = 31545468
- 89 + 31545379 = 31545468
- 137 + 31545331 = 31545468
- 139 + 31545329 = 31545468
- 151 + 31545317 = 31545468
- 181 + 31545287 = 31545468
Showing the first eight; more decompositions exist.
