Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71790, here are decompositions:

13 + 71777 = 71790
29 + 71761 = 71790
71 + 71719 = 71790
79 + 71711 = 71790
83 + 71707 = 71790
97 + 71693 = 71790
127 + 71663 = 71790
157 + 71633 = 71790

Showing the first eight; more decompositions exist.
