Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622394, here are decompositions:
- 5 + 31622389 = 31622394
- 17 + 31622377 = 31622394
- 47 + 31622347 = 31622394
- 101 + 31622293 = 31622394
- 107 + 31622287 = 31622394
- 113 + 31622281 = 31622394
- 137 + 31622257 = 31622394
- 157 + 31622237 = 31622394
Showing the first eight; more decompositions exist.
