Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504536, here are decompositions:

43 + 31504493 = 31504536
83 + 31504453 = 31504536
97 + 31504439 = 31504536
149 + 31504387 = 31504536
163 + 31504373 = 31504536
179 + 31504357 = 31504536
233 + 31504303 = 31504536
307 + 31504229 = 31504536

Showing the first eight; more decompositions exist.
