Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576524, here are decompositions:

13 + 31576511 = 31576524
41 + 31576483 = 31576524
47 + 31576477 = 31576524
71 + 31576453 = 31576524
97 + 31576427 = 31576524
107 + 31576417 = 31576524
113 + 31576411 = 31576524
151 + 31576373 = 31576524

Showing the first eight; more decompositions exist.
