Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545562, here are decompositions:
- 233 + 31545329 = 31545562
- 239 + 31545323 = 31545562
- 263 + 31545299 = 31545562
- 443 + 31545119 = 31545562
- 479 + 31545083 = 31545562
- 593 + 31544969 = 31545562
- 599 + 31544963 = 31545562
- 683 + 31544879 = 31545562
Showing the first eight; more decompositions exist.
