Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496576, here are decompositions:

3 + 31496573 = 31496576
37 + 31496539 = 31496576
127 + 31496449 = 31496576
157 + 31496419 = 31496576
283 + 31496293 = 31496576
313 + 31496263 = 31496576
367 + 31496209 = 31496576
457 + 31496119 = 31496576

Showing the first eight; more decompositions exist.
