Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475038, here are decompositions:
- 29 + 31475009 = 31475038
- 41 + 31474997 = 31475038
- 107 + 31474931 = 31475038
- 317 + 31474721 = 31475038
- 347 + 31474691 = 31475038
- 461 + 31474577 = 31475038
- 467 + 31474571 = 31475038
- 479 + 31474559 = 31475038
Showing the first eight; more decompositions exist.
