Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622072, here are decompositions:
- 109 + 31621963 = 31622072
- 193 + 31621879 = 31622072
- 241 + 31621831 = 31622072
- 379 + 31621693 = 31622072
- 421 + 31621651 = 31622072
- 439 + 31621633 = 31622072
- 541 + 31621531 = 31622072
- 571 + 31621501 = 31622072
Showing the first eight; more decompositions exist.
