Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536470, here are decompositions:
- 67 + 31536403 = 31536470
- 73 + 31536397 = 31536470
- 79 + 31536391 = 31536470
- 109 + 31536361 = 31536470
- 157 + 31536313 = 31536470
- 283 + 31536187 = 31536470
- 373 + 31536097 = 31536470
- 409 + 31536061 = 31536470
Showing the first eight; more decompositions exist.
