Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536408, here are decompositions:
- 5 + 31536403 = 31536408
- 11 + 31536397 = 31536408
- 17 + 31536391 = 31536408
- 47 + 31536361 = 31536408
- 61 + 31536347 = 31536408
- 181 + 31536227 = 31536408
- 307 + 31536101 = 31536408
- 311 + 31536097 = 31536408
Showing the first eight; more decompositions exist.
