Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619762, here are decompositions:

3 + 31619759 = 31619762
79 + 31619683 = 31619762
151 + 31619611 = 31619762
241 + 31619521 = 31619762
373 + 31619389 = 31619762
571 + 31619191 = 31619762
619 + 31619143 = 31619762
883 + 31618879 = 31619762

Showing the first eight; more decompositions exist.
