Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938018, here are decompositions:

127 + 937891 = 938018
199 + 937819 = 938018
229 + 937789 = 938018
241 + 937777 = 938018
271 + 937747 = 938018
337 + 937681 = 938018
379 + 937639 = 938018
541 + 937477 = 938018

Showing the first eight; more decompositions exist.
