Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461986, here are decompositions:
- 7 + 31461979 = 31461986
- 37 + 31461949 = 31461986
- 43 + 31461943 = 31461986
- 67 + 31461919 = 31461986
- 163 + 31461823 = 31461986
- 223 + 31461763 = 31461986
- 313 + 31461673 = 31461986
- 433 + 31461553 = 31461986
Showing the first eight; more decompositions exist.
