Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577496, here are decompositions:

23 + 31577473 = 31577496
79 + 31577417 = 31577496
103 + 31577393 = 31577496
107 + 31577389 = 31577496
109 + 31577387 = 31577496
113 + 31577383 = 31577496
127 + 31577369 = 31577496
173 + 31577323 = 31577496

Showing the first eight; more decompositions exist.
