Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528388, here are decompositions:

61 + 31528327 = 31528388
97 + 31528291 = 31528388
109 + 31528279 = 31528388
181 + 31528207 = 31528388
277 + 31528111 = 31528388
421 + 31527967 = 31528388
457 + 31527931 = 31528388
571 + 31527817 = 31528388

Showing the first eight; more decompositions exist.
