Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538632, here are decompositions:

3 + 31538629 = 31538632
53 + 31538579 = 31538632
71 + 31538561 = 31538632
479 + 31538153 = 31538632
491 + 31538141 = 31538632
569 + 31538063 = 31538632
599 + 31538033 = 31538632
743 + 31537889 = 31538632

Showing the first eight; more decompositions exist.
