Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576234, here are decompositions:

3 + 31576231 = 31576234
23 + 31576211 = 31576234
47 + 31576187 = 31576234
71 + 31576163 = 31576234
113 + 31576121 = 31576234
167 + 31576067 = 31576234
197 + 31576037 = 31576234
227 + 31576007 = 31576234

Showing the first eight; more decompositions exist.
