Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576482, here are decompositions:

5 + 31576477 = 31576482
23 + 31576459 = 31576482
29 + 31576453 = 31576482
43 + 31576439 = 31576482
71 + 31576411 = 31576482
73 + 31576409 = 31576482
79 + 31576403 = 31576482
109 + 31576373 = 31576482

Showing the first eight; more decompositions exist.
