Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938140, here are decompositions:

11 + 938129 = 938140
23 + 938117 = 938140
41 + 938099 = 938140
83 + 938057 = 938140
89 + 938051 = 938140
107 + 938033 = 938140
113 + 938027 = 938140
149 + 937991 = 938140

Showing the first eight; more decompositions exist.
