Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461518, here are decompositions:
- 31 + 31461487 = 31461518
- 37 + 31461481 = 31461518
- 61 + 31461457 = 31461518
- 157 + 31461361 = 31461518
- 337 + 31461181 = 31461518
- 541 + 31460977 = 31461518
- 547 + 31460971 = 31461518
- 601 + 31460917 = 31461518
Showing the first eight; more decompositions exist.
