Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540376, here are decompositions:
- 13 + 31540363 = 31540376
- 37 + 31540339 = 31540376
- 67 + 31540309 = 31540376
- 79 + 31540297 = 31540376
- 163 + 31540213 = 31540376
- 229 + 31540147 = 31540376
- 277 + 31540099 = 31540376
- 313 + 31540063 = 31540376
Showing the first eight; more decompositions exist.
