Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528322, here are decompositions:

31 + 31528291 = 31528322
43 + 31528279 = 31528322
109 + 31528213 = 31528322
151 + 31528171 = 31528322
211 + 31528111 = 31528322
229 + 31528093 = 31528322
409 + 31527913 = 31528322
541 + 31527781 = 31528322

Showing the first eight; more decompositions exist.
