Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537048, here are decompositions:
- 5 + 31537043 = 31537048
- 47 + 31537001 = 31537048
- 89 + 31536959 = 31537048
- 131 + 31536917 = 31537048
- 227 + 31536821 = 31537048
- 317 + 31536731 = 31537048
- 419 + 31536629 = 31537048
- 509 + 31536539 = 31537048
Showing the first eight; more decompositions exist.
