Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30744, here are decompositions:
- 17 + 30727 = 30744
- 31 + 30713 = 30744
- 37 + 30707 = 30744
- 41 + 30703 = 30744
- 47 + 30697 = 30744
- 67 + 30677 = 30744
- 73 + 30671 = 30744
- 83 + 30661 = 30744
Showing the first eight; more decompositions exist.
