Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532242, here are decompositions:

23 + 31532219 = 31532242
101 + 31532141 = 31532242
179 + 31532063 = 31532242
239 + 31532003 = 31532242
311 + 31531931 = 31532242
359 + 31531883 = 31532242
491 + 31531751 = 31532242
563 + 31531679 = 31532242

Showing the first eight; more decompositions exist.
