Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72424, here are decompositions:
- 3 + 72421 = 72424
- 41 + 72383 = 72424
- 71 + 72353 = 72424
- 83 + 72341 = 72424
- 137 + 72287 = 72424
- 173 + 72251 = 72424
- 197 + 72227 = 72424
- 251 + 72173 = 72424
Showing the first eight; more decompositions exist.
