Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589342, here are decompositions:
- 3 + 31589339 = 31589342
- 13 + 31589329 = 31589342
- 223 + 31589119 = 31589342
- 331 + 31589011 = 31589342
- 349 + 31588993 = 31589342
- 409 + 31588933 = 31589342
- 643 + 31588699 = 31589342
- 739 + 31588603 = 31589342
Showing the first eight; more decompositions exist.
