Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615692, here are decompositions:

23 + 31615669 = 31615692
29 + 31615663 = 31615692
41 + 31615651 = 31615692
83 + 31615609 = 31615692
89 + 31615603 = 31615692
103 + 31615589 = 31615692
109 + 31615583 = 31615692
149 + 31615543 = 31615692

Showing the first eight; more decompositions exist.
