Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504722, here are decompositions:

19 + 31504703 = 31504722
31 + 31504691 = 31504722
61 + 31504661 = 31504722
71 + 31504651 = 31504722
103 + 31504619 = 31504722
131 + 31504591 = 31504722
149 + 31504573 = 31504722
229 + 31504493 = 31504722

Showing the first eight; more decompositions exist.
