Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475152, here are decompositions:
- 11 + 31475141 = 31475152
- 41 + 31475111 = 31475152
- 53 + 31475099 = 31475152
- 83 + 31475069 = 31475152
- 389 + 31474763 = 31475152
- 419 + 31474733 = 31475152
- 431 + 31474721 = 31475152
- 461 + 31474691 = 31475152
Showing the first eight; more decompositions exist.
