Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123790, here are decompositions:

3 + 123787 = 123790
53 + 123737 = 123790
59 + 123731 = 123790
71 + 123719 = 123790
83 + 123707 = 123790
89 + 123701 = 123790
113 + 123677 = 123790
137 + 123653 = 123790

Showing the first eight; more decompositions exist.
