Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576336, here are decompositions:

47 + 31576289 = 31576336
53 + 31576283 = 31576336
83 + 31576253 = 31576336
137 + 31576199 = 31576336
149 + 31576187 = 31576336
167 + 31576169 = 31576336
173 + 31576163 = 31576336
269 + 31576067 = 31576336

Showing the first eight; more decompositions exist.
