Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738424, here are decompositions:

17 + 8738407 = 8738424
41 + 8738383 = 8738424
47 + 8738377 = 8738424
61 + 8738363 = 8738424
73 + 8738351 = 8738424
131 + 8738293 = 8738424
151 + 8738273 = 8738424
193 + 8738231 = 8738424

Showing the first eight; more decompositions exist.
