Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504466, here are decompositions:

13 + 31504453 = 31504466
79 + 31504387 = 31504466
109 + 31504357 = 31504466
139 + 31504327 = 31504466
163 + 31504303 = 31504466
277 + 31504189 = 31504466
283 + 31504183 = 31504466
337 + 31504129 = 31504466

Showing the first eight; more decompositions exist.
