Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747690, here are decompositions:

13 + 8747677 = 8747690
37 + 8747653 = 8747690
67 + 8747623 = 8747690
73 + 8747617 = 8747690
151 + 8747539 = 8747690
163 + 8747527 = 8747690
271 + 8747419 = 8747690
283 + 8747407 = 8747690

Showing the first eight; more decompositions exist.
