Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576484, here are decompositions:

7 + 31576477 = 31576484
31 + 31576453 = 31576484
67 + 31576417 = 31576484
73 + 31576411 = 31576484
223 + 31576261 = 31576484
283 + 31576201 = 31576484
367 + 31576117 = 31576484
397 + 31576087 = 31576484

Showing the first eight; more decompositions exist.
