Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605058, here are decompositions:

11 + 31605047 = 31605058
29 + 31605029 = 31605058
41 + 31605017 = 31605058
71 + 31604987 = 31605058
269 + 31604789 = 31605058
311 + 31604747 = 31605058
431 + 31604627 = 31605058
449 + 31604609 = 31605058

Showing the first eight; more decompositions exist.
