Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527632, here are decompositions:

109 + 31527523 = 31527632
151 + 31527481 = 31527632
379 + 31527253 = 31527632
421 + 31527211 = 31527632
439 + 31527193 = 31527632
523 + 31527109 = 31527632
691 + 31526941 = 31527632
733 + 31526899 = 31527632

Showing the first eight; more decompositions exist.
