Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619036, here are decompositions:

19 + 31619017 = 31619036
37 + 31618999 = 31619036
139 + 31618897 = 31619036
157 + 31618879 = 31619036
283 + 31618753 = 31619036
367 + 31618669 = 31619036
373 + 31618663 = 31619036
439 + 31618597 = 31619036

Showing the first eight; more decompositions exist.
