Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534020, here are decompositions:

41 + 31533979 = 31534020
53 + 31533967 = 31534020
61 + 31533959 = 31534020
71 + 31533949 = 31534020
97 + 31533923 = 31534020
101 + 31533919 = 31534020
109 + 31533911 = 31534020
149 + 31533871 = 31534020

Showing the first eight; more decompositions exist.
