Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737438, here are decompositions:

5 + 8737433 = 8737438
11 + 8737427 = 8737438
89 + 8737349 = 8737438
137 + 8737301 = 8737438
167 + 8737271 = 8737438
191 + 8737247 = 8737438
239 + 8737199 = 8737438
389 + 8737049 = 8737438

Showing the first eight; more decompositions exist.
