Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72438, here are decompositions:
- 7 + 72431 = 72438
- 17 + 72421 = 72438
- 59 + 72379 = 72438
- 71 + 72367 = 72438
- 97 + 72341 = 72438
- 101 + 72337 = 72438
- 131 + 72307 = 72438
- 151 + 72287 = 72438
Showing the first eight; more decompositions exist.
