Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72394, here are decompositions:
- 11 + 72383 = 72394
- 41 + 72353 = 72394
- 53 + 72341 = 72394
- 107 + 72287 = 72394
- 167 + 72227 = 72394
- 173 + 72221 = 72394
- 227 + 72167 = 72394
- 233 + 72161 = 72394
Showing the first eight; more decompositions exist.
