Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51742, here are decompositions:
- 23 + 51719 = 51742
- 29 + 51713 = 51742
- 59 + 51683 = 51742
- 83 + 51659 = 51742
- 149 + 51593 = 51742
- 179 + 51563 = 51742
- 191 + 51551 = 51742
- 239 + 51503 = 51742
Showing the first eight; more decompositions exist.
