Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577376, here are decompositions:

7 + 31577369 = 31577376
13 + 31577363 = 31577376
23 + 31577353 = 31577376
53 + 31577323 = 31577376
107 + 31577269 = 31577376
113 + 31577263 = 31577376
137 + 31577239 = 31577376
167 + 31577209 = 31577376

Showing the first eight; more decompositions exist.
