Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753438, here are decompositions:

37 + 8753401 = 8753438
79 + 8753359 = 8753438
181 + 8753257 = 8753438
241 + 8753197 = 8753438
277 + 8753161 = 8753438
349 + 8753089 = 8753438
367 + 8753071 = 8753438
787 + 8752651 = 8753438

Showing the first eight; more decompositions exist.
