Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528058, here are decompositions:

61 + 31527997 = 31528058
127 + 31527931 = 31528058
229 + 31527829 = 31528058
241 + 31527817 = 31528058
271 + 31527787 = 31528058
277 + 31527781 = 31528058
349 + 31527709 = 31528058
577 + 31527481 = 31528058

Showing the first eight; more decompositions exist.
