Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545604, here are decompositions:
- 5 + 31545599 = 31545604
- 197 + 31545407 = 31545604
- 281 + 31545323 = 31545604
- 317 + 31545287 = 31545604
- 383 + 31545221 = 31545604
- 521 + 31545083 = 31545604
- 641 + 31544963 = 31545604
- 821 + 31544783 = 31545604
Showing the first eight; more decompositions exist.
