Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504666, here are decompositions:

5 + 31504661 = 31504666
47 + 31504619 = 31504666
59 + 31504607 = 31504666
173 + 31504493 = 31504666
227 + 31504439 = 31504666
293 + 31504373 = 31504666
563 + 31504103 = 31504666
569 + 31504097 = 31504666

Showing the first eight; more decompositions exist.
