Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607864, here are decompositions:

7 + 31607857 = 31607864
73 + 31607791 = 31607864
181 + 31607683 = 31607864
193 + 31607671 = 31607864
283 + 31607581 = 31607864
313 + 31607551 = 31607864
523 + 31607341 = 31607864
571 + 31607293 = 31607864

Showing the first eight; more decompositions exist.
