Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504042, here are decompositions:

5 + 31504037 = 31504042
29 + 31504013 = 31504042
71 + 31503971 = 31504042
113 + 31503929 = 31504042
131 + 31503911 = 31504042
179 + 31503863 = 31504042
233 + 31503809 = 31504042
263 + 31503779 = 31504042

Showing the first eight; more decompositions exist.
