Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49440, here are decompositions:
- 7 + 49433 = 49440
- 11 + 49429 = 49440
- 23 + 49417 = 49440
- 29 + 49411 = 49440
- 31 + 49409 = 49440
- 47 + 49393 = 49440
- 71 + 49369 = 49440
- 73 + 49367 = 49440
Showing the first eight; more decompositions exist.
