Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619696, here are decompositions:

13 + 31619683 = 31619696
79 + 31619617 = 31619696
139 + 31619557 = 31619696
307 + 31619389 = 31619696
337 + 31619359 = 31619696
439 + 31619257 = 31619696
487 + 31619209 = 31619696
877 + 31618819 = 31619696

Showing the first eight; more decompositions exist.
