Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577592, here are decompositions:

5 + 31577587 = 31577592
61 + 31577531 = 31577592
71 + 31577521 = 31577592
83 + 31577509 = 31577592
191 + 31577401 = 31577592
199 + 31577393 = 31577592
223 + 31577369 = 31577592
229 + 31577363 = 31577592

Showing the first eight; more decompositions exist.
