Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938166, here are decompositions:

37 + 938129 = 938166
59 + 938107 = 938166
67 + 938099 = 938166
83 + 938083 = 938166
107 + 938059 = 938166
109 + 938057 = 938166
113 + 938053 = 938166
139 + 938027 = 938166

Showing the first eight; more decompositions exist.
