Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523036, here are decompositions:

163 + 31522873 = 31523036
367 + 31522669 = 31523036
373 + 31522663 = 31523036
379 + 31522657 = 31523036
439 + 31522597 = 31523036
487 + 31522549 = 31523036
577 + 31522459 = 31523036
673 + 31522363 = 31523036

Showing the first eight; more decompositions exist.
