Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534536, here are decompositions:
- 43 + 31534493 = 31534536
- 53 + 31534483 = 31534536
- 79 + 31534457 = 31534536
- 107 + 31534429 = 31534536
- 109 + 31534427 = 31534536
- 113 + 31534423 = 31534536
- 167 + 31534369 = 31534536
- 193 + 31534343 = 31534536
Showing the first eight; more decompositions exist.
