Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942138, here are decompositions:

37 + 942101 = 942138
47 + 942091 = 942138
59 + 942079 = 942138
89 + 942049 = 942138
97 + 942041 = 942138
101 + 942037 = 942138
107 + 942031 = 942138
139 + 941999 = 942138

Showing the first eight; more decompositions exist.
