Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738430, here are decompositions:

23 + 8738407 = 8738430
31 + 8738399 = 8738430
47 + 8738383 = 8738430
53 + 8738377 = 8738430
67 + 8738363 = 8738430
79 + 8738351 = 8738430
97 + 8738333 = 8738430
131 + 8738299 = 8738430

Showing the first eight; more decompositions exist.
