Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576546, here are decompositions:

5 + 31576541 = 31576546
17 + 31576529 = 31576546
107 + 31576439 = 31576546
137 + 31576409 = 31576546
173 + 31576373 = 31576546
179 + 31576367 = 31576546
257 + 31576289 = 31576546
263 + 31576283 = 31576546

Showing the first eight; more decompositions exist.
