Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577482, here are decompositions:

11 + 31577471 = 31577482
89 + 31577393 = 31577482
113 + 31577369 = 31577482
191 + 31577291 = 31577482
353 + 31577129 = 31577482
401 + 31577081 = 31577482
491 + 31576991 = 31577482
593 + 31576889 = 31577482

Showing the first eight; more decompositions exist.
