Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504102, here are decompositions:

5 + 31504097 = 31504102
89 + 31504013 = 31504102
131 + 31503971 = 31504102
173 + 31503929 = 31504102
191 + 31503911 = 31504102
239 + 31503863 = 31504102
293 + 31503809 = 31504102
353 + 31503749 = 31504102

Showing the first eight; more decompositions exist.
