Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72270, here are decompositions:
- 17 + 72253 = 72270
- 19 + 72251 = 72270
- 41 + 72229 = 72270
- 43 + 72227 = 72270
- 47 + 72223 = 72270
- 59 + 72211 = 72270
- 97 + 72173 = 72270
- 101 + 72169 = 72270
Showing the first eight; more decompositions exist.
