Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532056, here are decompositions:

53 + 31532003 = 31532056
89 + 31531967 = 31532056
173 + 31531883 = 31532056
239 + 31531817 = 31532056
389 + 31531667 = 31532056
599 + 31531457 = 31532056
653 + 31531403 = 31532056
839 + 31531217 = 31532056

Showing the first eight; more decompositions exist.
