Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536856, here are decompositions:
- 83 + 31536773 = 31536856
- 137 + 31536719 = 31536856
- 149 + 31536707 = 31536856
- 227 + 31536629 = 31536856
- 317 + 31536539 = 31536856
- 503 + 31536353 = 31536856
- 509 + 31536347 = 31536856
- 563 + 31536293 = 31536856
Showing the first eight; more decompositions exist.
