Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536432, here are decompositions:
- 29 + 31536403 = 31536432
- 41 + 31536391 = 31536432
- 71 + 31536361 = 31536432
- 73 + 31536359 = 31536432
- 79 + 31536353 = 31536432
- 139 + 31536293 = 31536432
- 229 + 31536203 = 31536432
- 271 + 31536161 = 31536432
Showing the first eight; more decompositions exist.
