Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474360, here are decompositions:

3 + 31474357 = 31474360
17 + 31474343 = 31474360
41 + 31474319 = 31474360
53 + 31474307 = 31474360
59 + 31474301 = 31474360
107 + 31474253 = 31474360
317 + 31474043 = 31474360
353 + 31474007 = 31474360

Showing the first eight; more decompositions exist.
