Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938172, here are decompositions:

43 + 938129 = 938172
73 + 938099 = 938172
83 + 938089 = 938172
89 + 938083 = 938172
101 + 938071 = 938172
113 + 938059 = 938172
139 + 938033 = 938172
149 + 938023 = 938172

Showing the first eight; more decompositions exist.
