Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729690, here are decompositions:

31 + 8729659 = 8729690
43 + 8729647 = 8729690
61 + 8729629 = 8729690
97 + 8729593 = 8729690
127 + 8729563 = 8729690
199 + 8729491 = 8729690
223 + 8729467 = 8729690
367 + 8729323 = 8729690

Showing the first eight; more decompositions exist.
