Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738486, here are decompositions:

13 + 8738473 = 8738486
37 + 8738449 = 8738486
79 + 8738407 = 8738486
103 + 8738383 = 8738486
109 + 8738377 = 8738486
193 + 8738293 = 8738486
223 + 8738263 = 8738486
277 + 8738209 = 8738486

Showing the first eight; more decompositions exist.
