Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532322, here are decompositions:

43 + 31532279 = 31532322
53 + 31532269 = 31532322
61 + 31532261 = 31532322
103 + 31532219 = 31532322
113 + 31532209 = 31532322
181 + 31532141 = 31532322
233 + 31532089 = 31532322
251 + 31532071 = 31532322

Showing the first eight; more decompositions exist.
