Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738528, here are decompositions:

37 + 8738491 = 8738528
79 + 8738449 = 8738528
151 + 8738377 = 8738528
229 + 8738299 = 8738528
367 + 8738161 = 8738528
439 + 8738089 = 8738528
457 + 8738071 = 8738528
607 + 8737921 = 8738528

Showing the first eight; more decompositions exist.
