Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625432, here are decompositions:
- 31 + 31625401 = 31625432
- 151 + 31625281 = 31625432
- 283 + 31625149 = 31625432
- 373 + 31625059 = 31625432
- 571 + 31624861 = 31625432
- 691 + 31624741 = 31625432
- 733 + 31624699 = 31625432
- 1009 + 31624423 = 31625432
Showing the first eight; more decompositions exist.
