Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476020, here are decompositions:

3 + 31476017 = 31476020
7 + 31476013 = 31476020
67 + 31475953 = 31476020
109 + 31475911 = 31476020
193 + 31475827 = 31476020
223 + 31475797 = 31476020
241 + 31475779 = 31476020
271 + 31475749 = 31476020

Showing the first eight; more decompositions exist.
