Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619876, here are decompositions:

7 + 31619869 = 31619876
163 + 31619713 = 31619876
193 + 31619683 = 31619876
229 + 31619647 = 31619876
349 + 31619527 = 31619876
367 + 31619509 = 31619876
487 + 31619389 = 31619876
619 + 31619257 = 31619876

Showing the first eight; more decompositions exist.
