Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938664, here are decompositions:

5 + 938659 = 938664
47 + 938617 = 938664
53 + 938611 = 938664
73 + 938591 = 938664
101 + 938563 = 938664
127 + 938537 = 938664
131 + 938533 = 938664
157 + 938507 = 938664

Showing the first eight; more decompositions exist.
