Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504248, here are decompositions:

19 + 31504229 = 31504248
29 + 31504219 = 31504248
47 + 31504201 = 31504248
59 + 31504189 = 31504248
151 + 31504097 = 31504248
197 + 31504051 = 31504248
211 + 31504037 = 31504248
271 + 31503977 = 31504248

Showing the first eight; more decompositions exist.
