Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71646, here are decompositions:
- 13 + 71633 = 71646
- 53 + 71593 = 71646
- 83 + 71563 = 71646
- 97 + 71549 = 71646
- 109 + 71537 = 71646
- 163 + 71483 = 71646
- 167 + 71479 = 71646
- 173 + 71473 = 71646
Showing the first eight; more decompositions exist.
