Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627360, here are decompositions:

3 + 31627357 = 31627360
41 + 31627319 = 31627360
71 + 31627289 = 31627360
113 + 31627247 = 31627360
227 + 31627133 = 31627360
239 + 31627121 = 31627360
269 + 31627091 = 31627360
353 + 31627007 = 31627360

Showing the first eight; more decompositions exist.
