Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72330, here are decompositions:
- 17 + 72313 = 72330
- 23 + 72307 = 72330
- 43 + 72287 = 72330
- 53 + 72277 = 72330
- 59 + 72271 = 72330
- 61 + 72269 = 72330
- 79 + 72251 = 72330
- 101 + 72229 = 72330
Showing the first eight; more decompositions exist.
