Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504682, here are decompositions:

31 + 31504651 = 31504682
109 + 31504573 = 31504682
229 + 31504453 = 31504682
331 + 31504351 = 31504682
379 + 31504303 = 31504682
463 + 31504219 = 31504682
499 + 31504183 = 31504682
631 + 31504051 = 31504682

Showing the first eight; more decompositions exist.
