Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546020, here are decompositions:

7 + 31546013 = 31546020
13 + 31546007 = 31546020
29 + 31545991 = 31546020
61 + 31545959 = 31546020
67 + 31545953 = 31546020
97 + 31545923 = 31546020
101 + 31545919 = 31546020
179 + 31545841 = 31546020

Showing the first eight; more decompositions exist.
