Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534036, here are decompositions:

3 + 31534033 = 31534036
113 + 31533923 = 31534036
197 + 31533839 = 31534036
263 + 31533773 = 31534036
449 + 31533587 = 31534036
503 + 31533533 = 31534036
587 + 31533449 = 31534036
647 + 31533389 = 31534036

Showing the first eight; more decompositions exist.
