Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474516, here are decompositions:

83 + 31474433 = 31474516
113 + 31474403 = 31474516
173 + 31474343 = 31474516
197 + 31474319 = 31474516
263 + 31474253 = 31474516
443 + 31474073 = 31474516
509 + 31474007 = 31474516
599 + 31473917 = 31474516

Showing the first eight; more decompositions exist.
