Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622448, here are decompositions:
- 19 + 31622429 = 31622448
- 59 + 31622389 = 31622448
- 71 + 31622377 = 31622448
- 79 + 31622369 = 31622448
- 101 + 31622347 = 31622448
- 167 + 31622281 = 31622448
- 191 + 31622257 = 31622448
- 211 + 31622237 = 31622448
Showing the first eight; more decompositions exist.
