Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576366, here are decompositions:

83 + 31576283 = 31576366
113 + 31576253 = 31576366
167 + 31576199 = 31576366
179 + 31576187 = 31576366
197 + 31576169 = 31576366
317 + 31576049 = 31576366
359 + 31576007 = 31576366
443 + 31575923 = 31576366

Showing the first eight; more decompositions exist.
