Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544618, here are decompositions:
- 31 + 31544587 = 31544618
- 67 + 31544551 = 31544618
- 109 + 31544509 = 31544618
- 271 + 31544347 = 31544618
- 307 + 31544311 = 31544618
- 337 + 31544281 = 31544618
- 397 + 31544221 = 31544618
- 439 + 31544179 = 31544618
Showing the first eight; more decompositions exist.
