Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619624, here are decompositions:

7 + 31619617 = 31619624
13 + 31619611 = 31619624
67 + 31619557 = 31619624
97 + 31619527 = 31619624
103 + 31619521 = 31619624
313 + 31619311 = 31619624
367 + 31619257 = 31619624
433 + 31619191 = 31619624

Showing the first eight; more decompositions exist.
