Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104638, here are decompositions:

41 + 104597 = 104638
59 + 104579 = 104638
89 + 104549 = 104638
101 + 104537 = 104638
167 + 104471 = 104638
179 + 104459 = 104638
239 + 104399 = 104638
257 + 104381 = 104638

Showing the first eight; more decompositions exist.
