Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504692, here are decompositions:

31 + 31504661 = 31504692
41 + 31504651 = 31504692
73 + 31504619 = 31504692
101 + 31504591 = 31504692
199 + 31504493 = 31504692
211 + 31504481 = 31504692
239 + 31504453 = 31504692
389 + 31504303 = 31504692

Showing the first eight; more decompositions exist.
