Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72628, here are decompositions:
- 5 + 72623 = 72628
- 11 + 72617 = 72628
- 131 + 72497 = 72628
- 167 + 72461 = 72628
- 197 + 72431 = 72628
- 359 + 72269 = 72628
- 401 + 72227 = 72628
- 461 + 72167 = 72628
Showing the first eight; more decompositions exist.
