Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504060, here are decompositions:

23 + 31504037 = 31504060
47 + 31504013 = 31504060
83 + 31503977 = 31504060
89 + 31503971 = 31504060
131 + 31503929 = 31504060
149 + 31503911 = 31504060
173 + 31503887 = 31504060
197 + 31503863 = 31504060

Showing the first eight; more decompositions exist.
