Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72214, here are decompositions:
- 3 + 72211 = 72214
- 41 + 72173 = 72214
- 47 + 72167 = 72214
- 53 + 72161 = 72214
- 113 + 72101 = 72214
- 137 + 72077 = 72214
- 167 + 72047 = 72214
- 227 + 71987 = 72214
Showing the first eight; more decompositions exist.
