Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72272, here are decompositions:
- 3 + 72269 = 72272
- 19 + 72253 = 72272
- 43 + 72229 = 72272
- 61 + 72211 = 72272
- 103 + 72169 = 72272
- 163 + 72109 = 72272
- 181 + 72091 = 72272
- 199 + 72073 = 72272
Showing the first eight; more decompositions exist.
