Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938918, here are decompositions:

37 + 938881 = 938918
61 + 938857 = 938918
157 + 938761 = 938918
241 + 938677 = 938918
307 + 938611 = 938918
349 + 938569 = 938918
571 + 938347 = 938918
577 + 938341 = 938918

Showing the first eight; more decompositions exist.
