Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504150, here are decompositions:

17 + 31504133 = 31504150
23 + 31504127 = 31504150
47 + 31504103 = 31504150
53 + 31504097 = 31504150
113 + 31504037 = 31504150
137 + 31504013 = 31504150
173 + 31503977 = 31504150
179 + 31503971 = 31504150

Showing the first eight; more decompositions exist.
