Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606232, here are decompositions:

181 + 31606051 = 31606232
409 + 31605823 = 31606232
421 + 31605811 = 31606232
613 + 31605619 = 31606232
661 + 31605571 = 31606232
883 + 31605349 = 31606232
1051 + 31605181 = 31606232
1063 + 31605169 = 31606232

Showing the first eight; more decompositions exist.
