Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504124, here are decompositions:

37 + 31504087 = 31504124
73 + 31504051 = 31504124
151 + 31503973 = 31504124
163 + 31503961 = 31504124
193 + 31503931 = 31504124
241 + 31503883 = 31504124
271 + 31503853 = 31504124
277 + 31503847 = 31504124

Showing the first eight; more decompositions exist.
