Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468616, here are decompositions:

19 + 31468597 = 31468616
43 + 31468573 = 31468616
73 + 31468543 = 31468616
163 + 31468453 = 31468616
373 + 31468243 = 31468616
457 + 31468159 = 31468616
769 + 31467847 = 31468616
787 + 31467829 = 31468616

Showing the first eight; more decompositions exist.
