Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473708, here are decompositions:

5 + 31473703 = 31473708
109 + 31473599 = 31473708
127 + 31473581 = 31473708
179 + 31473529 = 31473708
229 + 31473479 = 31473708
251 + 31473457 = 31473708
271 + 31473437 = 31473708
311 + 31473397 = 31473708

Showing the first eight; more decompositions exist.
