Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458192, here are decompositions:

5 + 31458187 = 31458192
19 + 31458173 = 31458192
23 + 31458169 = 31458192
61 + 31458131 = 31458192
79 + 31458113 = 31458192
109 + 31458083 = 31458192
131 + 31458061 = 31458192
179 + 31458013 = 31458192

Showing the first eight; more decompositions exist.
