Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931142, here are decompositions:

13 + 931129 = 931142
19 + 931123 = 931142
139 + 931003 = 931142
151 + 930991 = 931142
211 + 930931 = 931142
283 + 930859 = 931142
379 + 930763 = 931142
523 + 930619 = 931142

Showing the first eight; more decompositions exist.
