Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459146, here are decompositions:

13 + 31459133 = 31459146
23 + 31459123 = 31459146
53 + 31459093 = 31459146
73 + 31459073 = 31459146
83 + 31459063 = 31459146
127 + 31459019 = 31459146
163 + 31458983 = 31459146
179 + 31458967 = 31459146

Showing the first eight; more decompositions exist.
