Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504032, here are decompositions:

19 + 31504013 = 31504032
59 + 31503973 = 31504032
61 + 31503971 = 31504032
71 + 31503961 = 31504032
101 + 31503931 = 31504032
103 + 31503929 = 31504032
149 + 31503883 = 31504032
179 + 31503853 = 31504032

Showing the first eight; more decompositions exist.
