Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475344, here are decompositions:
- 3 + 31475341 = 31475344
- 23 + 31475321 = 31475344
- 101 + 31475243 = 31475344
- 113 + 31475231 = 31475344
- 233 + 31475111 = 31475344
- 347 + 31474997 = 31475344
- 653 + 31474691 = 31475344
- 743 + 31474601 = 31475344
Showing the first eight; more decompositions exist.
