Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465942, here are decompositions:
- 113 + 31465829 = 31465942
- 269 + 31465673 = 31465942
- 281 + 31465661 = 31465942
- 293 + 31465649 = 31465942
- 311 + 31465631 = 31465942
- 461 + 31465481 = 31465942
- 491 + 31465451 = 31465942
- 653 + 31465289 = 31465942
Showing the first eight; more decompositions exist.
