Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485162, here are decompositions:

41 + 31485121 = 31485162
61 + 31485101 = 31485162
83 + 31485079 = 31485162
103 + 31485059 = 31485162
113 + 31485049 = 31485162
131 + 31485031 = 31485162
139 + 31485023 = 31485162
173 + 31484989 = 31485162

Showing the first eight; more decompositions exist.
