Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625440, here are decompositions:
- 29 + 31625411 = 31625440
- 47 + 31625393 = 31625440
- 59 + 31625381 = 31625440
- 89 + 31625351 = 31625440
- 137 + 31625303 = 31625440
- 179 + 31625261 = 31625440
- 293 + 31625147 = 31625440
- 383 + 31625057 = 31625440
Showing the first eight; more decompositions exist.
