Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504018, here are decompositions:

5 + 31504013 = 31504018
41 + 31503977 = 31504018
47 + 31503971 = 31504018
89 + 31503929 = 31504018
101 + 31503917 = 31504018
107 + 31503911 = 31504018
131 + 31503887 = 31504018
239 + 31503779 = 31504018

Showing the first eight; more decompositions exist.
