Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532236, here are decompositions:

17 + 31532219 = 31532236
173 + 31532063 = 31532236
233 + 31532003 = 31532236
269 + 31531967 = 31532236
353 + 31531883 = 31532236
419 + 31531817 = 31532236
509 + 31531727 = 31532236
557 + 31531679 = 31532236

Showing the first eight; more decompositions exist.
