Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576466, here are decompositions:

7 + 31576459 = 31576466
13 + 31576453 = 31576466
199 + 31576267 = 31576466
349 + 31576117 = 31576466
379 + 31576087 = 31576466
457 + 31576009 = 31576466
463 + 31576003 = 31576466
643 + 31575823 = 31576466

Showing the first eight; more decompositions exist.
