Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542832, here are decompositions:

3 + 31542829 = 31542832
5 + 31542827 = 31542832
23 + 31542809 = 31542832
173 + 31542659 = 31542832
353 + 31542479 = 31542832
491 + 31542341 = 31542832
509 + 31542323 = 31542832
599 + 31542233 = 31542832

Showing the first eight; more decompositions exist.
