Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536772, here are decompositions:
- 41 + 31536731 = 31536772
- 53 + 31536719 = 31536772
- 233 + 31536539 = 31536772
- 251 + 31536521 = 31536772
- 389 + 31536383 = 31536772
- 419 + 31536353 = 31536772
- 479 + 31536293 = 31536772
- 569 + 31536203 = 31536772
Showing the first eight; more decompositions exist.
