Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545928, here are decompositions:
- 5 + 31545923 = 31545928
- 41 + 31545887 = 31545928
- 179 + 31545749 = 31545928
- 191 + 31545737 = 31545928
- 317 + 31545611 = 31545928
- 521 + 31545407 = 31545928
- 599 + 31545329 = 31545928
- 641 + 31545287 = 31545928
Showing the first eight; more decompositions exist.
