Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72264, here are decompositions:
- 11 + 72253 = 72264
- 13 + 72251 = 72264
- 37 + 72227 = 72264
- 41 + 72223 = 72264
- 43 + 72221 = 72264
- 53 + 72211 = 72264
- 97 + 72167 = 72264
- 103 + 72161 = 72264
Showing the first eight; more decompositions exist.
