Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536618, here are decompositions:
- 5 + 31536613 = 31536618
- 11 + 31536607 = 31536618
- 67 + 31536551 = 31536618
- 79 + 31536539 = 31536618
- 89 + 31536529 = 31536618
- 97 + 31536521 = 31536618
- 137 + 31536481 = 31536618
- 227 + 31536391 = 31536618
Showing the first eight; more decompositions exist.
