Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708790, here are decompositions:

59 + 8708731 = 8708790
73 + 8708717 = 8708790
89 + 8708701 = 8708790
127 + 8708663 = 8708790
151 + 8708639 = 8708790
163 + 8708627 = 8708790
173 + 8708617 = 8708790
179 + 8708611 = 8708790

Showing the first eight; more decompositions exist.
