Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504308, here are decompositions:

5 + 31504303 = 31504308
79 + 31504229 = 31504308
89 + 31504219 = 31504308
107 + 31504201 = 31504308
179 + 31504129 = 31504308
181 + 31504127 = 31504308
211 + 31504097 = 31504308
257 + 31504051 = 31504308

Showing the first eight; more decompositions exist.
