Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576294, here are decompositions:

5 + 31576289 = 31576294
11 + 31576283 = 31576294
41 + 31576253 = 31576294
53 + 31576241 = 31576294
83 + 31576211 = 31576294
107 + 31576187 = 31576294
131 + 31576163 = 31576294
173 + 31576121 = 31576294

Showing the first eight; more decompositions exist.
