Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504188, here are decompositions:

5 + 31504183 = 31504188
59 + 31504129 = 31504188
61 + 31504127 = 31504188
101 + 31504087 = 31504188
137 + 31504051 = 31504188
151 + 31504037 = 31504188
211 + 31503977 = 31504188
227 + 31503961 = 31504188

Showing the first eight; more decompositions exist.
