Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582646, here are decompositions:
- 13 + 31582633 = 31582646
- 19 + 31582627 = 31582646
- 37 + 31582609 = 31582646
- 157 + 31582489 = 31582646
- 229 + 31582417 = 31582646
- 313 + 31582333 = 31582646
- 379 + 31582267 = 31582646
- 397 + 31582249 = 31582646
Showing the first eight; more decompositions exist.
