Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576576, here are decompositions:

47 + 31576529 = 31576576
137 + 31576439 = 31576576
149 + 31576427 = 31576576
167 + 31576409 = 31576576
173 + 31576403 = 31576576
293 + 31576283 = 31576576
389 + 31576187 = 31576576
509 + 31576067 = 31576576

Showing the first eight; more decompositions exist.
