Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534564, here are decompositions:

3 + 31534561 = 31534564
11 + 31534553 = 31534564
71 + 31534493 = 31534564
107 + 31534457 = 31534564
137 + 31534427 = 31534564
263 + 31534301 = 31534564
293 + 31534271 = 31534564
317 + 31534247 = 31534564

Showing the first eight; more decompositions exist.
