Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938158, here are decompositions:

29 + 938129 = 938158
41 + 938117 = 938158
59 + 938099 = 938158
101 + 938057 = 938158
107 + 938051 = 938158
131 + 938027 = 938158
167 + 937991 = 938158
239 + 937919 = 938158

Showing the first eight; more decompositions exist.
