Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601750, here are decompositions:
- 7 + 31601743 = 31601750
- 43 + 31601707 = 31601750
- 79 + 31601671 = 31601750
- 181 + 31601569 = 31601750
- 199 + 31601551 = 31601750
- 211 + 31601539 = 31601750
- 223 + 31601527 = 31601750
- 241 + 31601509 = 31601750
Showing the first eight; more decompositions exist.
