Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504704, here are decompositions:

13 + 31504691 = 31504704
37 + 31504667 = 31504704
43 + 31504661 = 31504704
53 + 31504651 = 31504704
97 + 31504607 = 31504704
113 + 31504591 = 31504704
131 + 31504573 = 31504704
137 + 31504567 = 31504704

Showing the first eight; more decompositions exist.
