Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72646, here are decompositions:
- 3 + 72643 = 72646
- 23 + 72623 = 72646
- 29 + 72617 = 72646
- 113 + 72533 = 72646
- 149 + 72497 = 72646
- 179 + 72467 = 72646
- 263 + 72383 = 72646
- 293 + 72353 = 72646
Showing the first eight; more decompositions exist.
