Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723790, here are decompositions:

59 + 8723731 = 8723790
83 + 8723707 = 8723790
113 + 8723677 = 8723790
137 + 8723653 = 8723790
151 + 8723639 = 8723790
181 + 8723609 = 8723790
197 + 8723593 = 8723790
239 + 8723551 = 8723790

Showing the first eight; more decompositions exist.
