Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577014, here are decompositions:

5 + 31577009 = 31577014
23 + 31576991 = 31577014
47 + 31576967 = 31577014
83 + 31576931 = 31577014
113 + 31576901 = 31577014
263 + 31576751 = 31577014
311 + 31576703 = 31577014
431 + 31576583 = 31577014

Showing the first eight; more decompositions exist.
