Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504152, here are decompositions:

19 + 31504133 = 31504152
23 + 31504129 = 31504152
101 + 31504051 = 31504152
139 + 31504013 = 31504152
179 + 31503973 = 31504152
181 + 31503971 = 31504152
191 + 31503961 = 31504152
223 + 31503929 = 31504152

Showing the first eight; more decompositions exist.
