Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625880, here are decompositions:
- 31 + 31625849 = 31625880
- 37 + 31625843 = 31625880
- 59 + 31625821 = 31625880
- 61 + 31625819 = 31625880
- 73 + 31625807 = 31625880
- 101 + 31625779 = 31625880
- 103 + 31625777 = 31625880
- 107 + 31625773 = 31625880
Showing the first eight; more decompositions exist.
