Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473666, here are decompositions:

67 + 31473599 = 31473666
73 + 31473593 = 31473666
83 + 31473583 = 31473666
137 + 31473529 = 31473666
179 + 31473487 = 31473666
229 + 31473437 = 31473666
269 + 31473397 = 31473666
307 + 31473359 = 31473666

Showing the first eight; more decompositions exist.
