Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536862, here are decompositions:
- 41 + 31536821 = 31536862
- 89 + 31536773 = 31536862
- 131 + 31536731 = 31536862
- 233 + 31536629 = 31536862
- 311 + 31536551 = 31536862
- 479 + 31536383 = 31536862
- 503 + 31536359 = 31536862
- 509 + 31536353 = 31536862
Showing the first eight; more decompositions exist.
