Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104628, here are decompositions:

5 + 104623 = 104628
31 + 104597 = 104628
67 + 104561 = 104628
79 + 104549 = 104628
101 + 104527 = 104628
137 + 104491 = 104628
149 + 104479 = 104628
157 + 104471 = 104628

Showing the first eight; more decompositions exist.
