Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523636, here are decompositions:

3 + 31523633 = 31523636
37 + 31523599 = 31523636
97 + 31523539 = 31523636
163 + 31523473 = 31523636
229 + 31523407 = 31523636
307 + 31523329 = 31523636
409 + 31523227 = 31523636
523 + 31523113 = 31523636

Showing the first eight; more decompositions exist.
