Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528334, here are decompositions:

7 + 31528327 = 31528334
43 + 31528291 = 31528334
67 + 31528267 = 31528334
127 + 31528207 = 31528334
163 + 31528171 = 31528334
223 + 31528111 = 31528334
241 + 31528093 = 31528334
337 + 31527997 = 31528334

Showing the first eight; more decompositions exist.
