Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931878, here are decompositions:

5 + 931873 = 931878
19 + 931859 = 931878
29 + 931849 = 931878
41 + 931837 = 931878
67 + 931811 = 931878
89 + 931789 = 931878
97 + 931781 = 931878
127 + 931751 = 931878

Showing the first eight; more decompositions exist.
