Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504716, here are decompositions:

13 + 31504703 = 31504716
97 + 31504619 = 31504716
109 + 31504607 = 31504716
149 + 31504567 = 31504716
223 + 31504493 = 31504716
263 + 31504453 = 31504716
277 + 31504439 = 31504716
349 + 31504367 = 31504716

Showing the first eight; more decompositions exist.
