Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456360, here are decompositions:

29 + 31456331 = 31456360
41 + 31456319 = 31456360
83 + 31456277 = 31456360
101 + 31456259 = 31456360
113 + 31456247 = 31456360
167 + 31456193 = 31456360
197 + 31456163 = 31456360
239 + 31456121 = 31456360

Showing the first eight; more decompositions exist.
