Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759438, here are decompositions:

19 + 8759419 = 8759438
31 + 8759407 = 8759438
67 + 8759371 = 8759438
139 + 8759299 = 8759438
151 + 8759287 = 8759438
271 + 8759167 = 8759438
277 + 8759161 = 8759438
349 + 8759089 = 8759438

Showing the first eight; more decompositions exist.
