Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540330, here are decompositions:
- 89 + 31540241 = 31540330
- 113 + 31540217 = 31540330
- 149 + 31540181 = 31540330
- 167 + 31540163 = 31540330
- 317 + 31540013 = 31540330
- 359 + 31539971 = 31540330
- 467 + 31539863 = 31540330
- 491 + 31539839 = 31540330
Showing the first eight; more decompositions exist.
