Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72230, here are decompositions:
- 3 + 72227 = 72230
- 7 + 72223 = 72230
- 19 + 72211 = 72230
- 61 + 72169 = 72230
- 127 + 72103 = 72230
- 139 + 72091 = 72230
- 157 + 72073 = 72230
- 199 + 72031 = 72230
Showing the first eight; more decompositions exist.
