Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576564, here are decompositions:

23 + 31576541 = 31576564
53 + 31576511 = 31576564
137 + 31576427 = 31576564
191 + 31576373 = 31576564
197 + 31576367 = 31576564
281 + 31576283 = 31576564
311 + 31576253 = 31576564
353 + 31576211 = 31576564

Showing the first eight; more decompositions exist.
