Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590032, here are decompositions:

79 + 31589953 = 31590032
109 + 31589923 = 31590032
163 + 31589869 = 31590032
349 + 31589683 = 31590032
373 + 31589659 = 31590032
421 + 31589611 = 31590032
571 + 31589461 = 31590032
631 + 31589401 = 31590032

Showing the first eight; more decompositions exist.
