Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534592, here are decompositions:

3 + 31534589 = 31534592
31 + 31534561 = 31534592
109 + 31534483 = 31534592
151 + 31534441 = 31534592
163 + 31534429 = 31534592
181 + 31534411 = 31534592
223 + 31534369 = 31534592
409 + 31534183 = 31534592

Showing the first eight; more decompositions exist.
