Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601984, here are decompositions:
- 61 + 31601923 = 31601984
- 103 + 31601881 = 31601984
- 241 + 31601743 = 31601984
- 277 + 31601707 = 31601984
- 313 + 31601671 = 31601984
- 433 + 31601551 = 31601984
- 457 + 31601527 = 31601984
- 577 + 31601407 = 31601984
Showing the first eight; more decompositions exist.
