Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576632, here are decompositions:

13 + 31576619 = 31576632
53 + 31576579 = 31576632
83 + 31576549 = 31576632
103 + 31576529 = 31576632
149 + 31576483 = 31576632
173 + 31576459 = 31576632
179 + 31576453 = 31576632
193 + 31576439 = 31576632

Showing the first eight; more decompositions exist.
