Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504020, here are decompositions:

7 + 31504013 = 31504020
43 + 31503977 = 31504020
47 + 31503973 = 31504020
59 + 31503961 = 31504020
89 + 31503931 = 31504020
103 + 31503917 = 31504020
109 + 31503911 = 31504020
137 + 31503883 = 31504020

Showing the first eight; more decompositions exist.
