Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577534, here are decompositions:

3 + 31577531 = 31577534
7 + 31577527 = 31577534
13 + 31577521 = 31577534
61 + 31577473 = 31577534
151 + 31577383 = 31577534
181 + 31577353 = 31577534
211 + 31577323 = 31577534
271 + 31577263 = 31577534

Showing the first eight; more decompositions exist.
