Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28548, here are decompositions:
- 7 + 28541 = 28548
- 11 + 28537 = 28548
- 31 + 28517 = 28548
- 71 + 28477 = 28548
- 101 + 28447 = 28548
- 109 + 28439 = 28548
- 137 + 28411 = 28548
- 139 + 28409 = 28548
Showing the first eight; more decompositions exist.
