Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576662, here are decompositions:

23 + 31576639 = 31576662
43 + 31576619 = 31576662
79 + 31576583 = 31576662
83 + 31576579 = 31576662
113 + 31576549 = 31576662
151 + 31576511 = 31576662
179 + 31576483 = 31576662
223 + 31576439 = 31576662

Showing the first eight; more decompositions exist.
