Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938660, here are decompositions:

43 + 938617 = 938660
97 + 938563 = 938660
127 + 938533 = 938660
223 + 938437 = 938660
313 + 938347 = 938660
337 + 938323 = 938660
367 + 938293 = 938660
397 + 938263 = 938660

Showing the first eight; more decompositions exist.
