Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938690, here are decompositions:

13 + 938677 = 938690
31 + 938659 = 938690
73 + 938617 = 938690
79 + 938611 = 938690
127 + 938563 = 938690
157 + 938533 = 938690
199 + 938491 = 938690
331 + 938359 = 938690

Showing the first eight; more decompositions exist.
