Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576652, here are decompositions:

13 + 31576639 = 31576652
73 + 31576579 = 31576652
103 + 31576549 = 31576652
193 + 31576459 = 31576652
199 + 31576453 = 31576652
241 + 31576411 = 31576652
421 + 31576231 = 31576652
433 + 31576219 = 31576652

Showing the first eight; more decompositions exist.
