Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536582, here are decompositions:
- 31 + 31536551 = 31536582
- 43 + 31536539 = 31536582
- 53 + 31536529 = 31536582
- 61 + 31536521 = 31536582
- 83 + 31536499 = 31536582
- 101 + 31536481 = 31536582
- 179 + 31536403 = 31536582
- 191 + 31536391 = 31536582
Showing the first eight; more decompositions exist.
