Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528088, here are decompositions:

19 + 31528069 = 31528088
157 + 31527931 = 31528088
271 + 31527817 = 31528088
307 + 31527781 = 31528088
379 + 31527709 = 31528088
547 + 31527541 = 31528088
607 + 31527481 = 31528088
811 + 31527277 = 31528088

Showing the first eight; more decompositions exist.
