Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473516, here are decompositions:

29 + 31473487 = 31473516
37 + 31473479 = 31473516
59 + 31473457 = 31473516
79 + 31473437 = 31473516
103 + 31473413 = 31473516
157 + 31473359 = 31473516
233 + 31473283 = 31473516
307 + 31473209 = 31473516

Showing the first eight; more decompositions exist.
