Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938626, here are decompositions:

53 + 938573 = 938626
89 + 938537 = 938626
167 + 938459 = 938626
173 + 938453 = 938626
179 + 938447 = 938626
233 + 938393 = 938626
239 + 938387 = 938626
257 + 938369 = 938626

Showing the first eight; more decompositions exist.
