Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945138, here are decompositions:

79 + 945059 = 945138
101 + 945037 = 945138
107 + 945031 = 945138
151 + 944987 = 945138
239 + 944899 = 945138
241 + 944897 = 945138
251 + 944887 = 945138
281 + 944857 = 945138

Showing the first eight; more decompositions exist.
