Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505652, here are decompositions:

19 + 31505633 = 31505652
29 + 31505623 = 31505652
43 + 31505609 = 31505652
53 + 31505599 = 31505652
83 + 31505569 = 31505652
131 + 31505521 = 31505652
151 + 31505501 = 31505652
163 + 31505489 = 31505652

Showing the first eight; more decompositions exist.
