Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545442, here are decompositions:
- 3 + 31545439 = 31545442
- 41 + 31545401 = 31545442
- 113 + 31545329 = 31545442
- 251 + 31545191 = 31545442
- 359 + 31545083 = 31545442
- 419 + 31545023 = 31545442
- 479 + 31544963 = 31545442
- 563 + 31544879 = 31545442
Showing the first eight; more decompositions exist.
