Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488832, here are decompositions:

5 + 31488827 = 31488832
269 + 31488563 = 31488832
461 + 31488371 = 31488832
503 + 31488329 = 31488832
509 + 31488323 = 31488832
743 + 31488089 = 31488832
761 + 31488071 = 31488832
773 + 31488059 = 31488832

Showing the first eight; more decompositions exist.
