Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143790, here are decompositions:

11 + 143779 = 143790
47 + 143743 = 143790
61 + 143729 = 143790
71 + 143719 = 143790
79 + 143711 = 143790
103 + 143687 = 143790
113 + 143677 = 143790
137 + 143653 = 143790

Showing the first eight; more decompositions exist.
