Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72412, here are decompositions:
- 29 + 72383 = 72412
- 59 + 72353 = 72412
- 71 + 72341 = 72412
- 191 + 72221 = 72412
- 239 + 72173 = 72412
- 251 + 72161 = 72412
- 311 + 72101 = 72412
- 359 + 72053 = 72412
Showing the first eight; more decompositions exist.
