Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576606, here are decompositions:

23 + 31576583 = 31576606
167 + 31576439 = 31576606
179 + 31576427 = 31576606
197 + 31576409 = 31576606
233 + 31576373 = 31576606
239 + 31576367 = 31576606
317 + 31576289 = 31576606
353 + 31576253 = 31576606

Showing the first eight; more decompositions exist.
