Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496856, here are decompositions:

29 + 31496827 = 31496856
37 + 31496819 = 31496856
47 + 31496809 = 31496856
73 + 31496783 = 31496856
137 + 31496719 = 31496856
163 + 31496693 = 31496856
179 + 31496677 = 31496856
257 + 31496599 = 31496856

Showing the first eight; more decompositions exist.
