Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625254, here are decompositions:
- 107 + 31625147 = 31625254
- 197 + 31625057 = 31625254
- 347 + 31624907 = 31625254
- 491 + 31624763 = 31625254
- 593 + 31624661 = 31625254
- 641 + 31624613 = 31625254
- 743 + 31624511 = 31625254
- 797 + 31624457 = 31625254
Showing the first eight; more decompositions exist.
