Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738386, here are decompositions:

3 + 8738383 = 8738386
23 + 8738363 = 8738386
47 + 8738339 = 8738386
53 + 8738333 = 8738386
113 + 8738273 = 8738386
257 + 8738129 = 8738386
263 + 8738123 = 8738386
353 + 8738033 = 8738386

Showing the first eight; more decompositions exist.
