Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738492, here are decompositions:

19 + 8738473 = 8738492
43 + 8738449 = 8738492
109 + 8738383 = 8738492
193 + 8738299 = 8738492
199 + 8738293 = 8738492
211 + 8738281 = 8738492
229 + 8738263 = 8738492
283 + 8738209 = 8738492

Showing the first eight; more decompositions exist.
