Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605692, here are decompositions:

3 + 31605689 = 31605692
73 + 31605619 = 31605692
109 + 31605583 = 31605692
331 + 31605361 = 31605692
373 + 31605319 = 31605692
421 + 31605271 = 31605692
463 + 31605229 = 31605692
523 + 31605169 = 31605692

Showing the first eight; more decompositions exist.
