Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938618, here are decompositions:

7 + 938611 = 938618
127 + 938491 = 938618
181 + 938437 = 938618
271 + 938347 = 938618
277 + 938341 = 938618
367 + 938251 = 938618
547 + 938071 = 938618
601 + 938017 = 938618

Showing the first eight; more decompositions exist.
