Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504218, here are decompositions:

17 + 31504201 = 31504218
29 + 31504189 = 31504218
89 + 31504129 = 31504218
131 + 31504087 = 31504218
167 + 31504051 = 31504218
181 + 31504037 = 31504218
241 + 31503977 = 31504218
257 + 31503961 = 31504218

Showing the first eight; more decompositions exist.
