Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473690, here are decompositions:

97 + 31473593 = 31473690
107 + 31473583 = 31473690
109 + 31473581 = 31473690
167 + 31473523 = 31473690
211 + 31473479 = 31473690
233 + 31473457 = 31473690
277 + 31473413 = 31473690
293 + 31473397 = 31473690

Showing the first eight; more decompositions exist.
