Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72234, here are decompositions:
- 5 + 72229 = 72234
- 7 + 72227 = 72234
- 11 + 72223 = 72234
- 13 + 72221 = 72234
- 23 + 72211 = 72234
- 61 + 72173 = 72234
- 67 + 72167 = 72234
- 73 + 72161 = 72234
Showing the first eight; more decompositions exist.
