Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510162, here are decompositions:

23 + 31510139 = 31510162
29 + 31510133 = 31510162
41 + 31510121 = 31510162
71 + 31510091 = 31510162
83 + 31510079 = 31510162
191 + 31509971 = 31510162
269 + 31509893 = 31510162
311 + 31509851 = 31510162

Showing the first eight; more decompositions exist.
