Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468020, here are decompositions:

7 + 31468013 = 31468020
19 + 31468001 = 31468020
37 + 31467983 = 31468020
53 + 31467967 = 31468020
71 + 31467949 = 31468020
83 + 31467937 = 31468020
109 + 31467911 = 31468020
127 + 31467893 = 31468020

Showing the first eight; more decompositions exist.
