Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72748, here are decompositions:
- 29 + 72719 = 72748
- 41 + 72707 = 72748
- 47 + 72701 = 72748
- 59 + 72689 = 72748
- 101 + 72647 = 72748
- 131 + 72617 = 72748
- 197 + 72551 = 72748
- 251 + 72497 = 72748
Showing the first eight; more decompositions exist.
