Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528238, here are decompositions:

31 + 31528207 = 31528238
67 + 31528171 = 31528238
127 + 31528111 = 31528238
241 + 31527997 = 31528238
271 + 31527967 = 31528238
307 + 31527931 = 31528238
409 + 31527829 = 31528238
421 + 31527817 = 31528238

Showing the first eight; more decompositions exist.
