Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938646, here are decompositions:

29 + 938617 = 938646
73 + 938573 = 938646
83 + 938563 = 938646
109 + 938537 = 938646
113 + 938533 = 938646
139 + 938507 = 938646
193 + 938453 = 938646
199 + 938447 = 938646

Showing the first eight; more decompositions exist.
