Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504082, here are decompositions:

31 + 31504051 = 31504082
109 + 31503973 = 31504082
151 + 31503931 = 31504082
199 + 31503883 = 31504082
229 + 31503853 = 31504082
241 + 31503841 = 31504082
271 + 31503811 = 31504082
283 + 31503799 = 31504082

Showing the first eight; more decompositions exist.
