Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461782, here are decompositions:
- 3 + 31461779 = 31461782
- 19 + 31461763 = 31461782
- 109 + 31461673 = 31461782
- 211 + 31461571 = 31461782
- 229 + 31461553 = 31461782
- 379 + 31461403 = 31461782
- 421 + 31461361 = 31461782
- 433 + 31461349 = 31461782
Showing the first eight; more decompositions exist.
