Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577576, here are decompositions:

67 + 31577509 = 31577576
103 + 31577473 = 31577576
193 + 31577383 = 31577576
223 + 31577353 = 31577576
307 + 31577269 = 31577576
313 + 31577263 = 31577576
337 + 31577239 = 31577576
367 + 31577209 = 31577576

Showing the first eight; more decompositions exist.
