Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473668, here are decompositions:

139 + 31473529 = 31473668
181 + 31473487 = 31473668
211 + 31473457 = 31473668
271 + 31473397 = 31473668
337 + 31473331 = 31473668
601 + 31473067 = 31473668
607 + 31473061 = 31473668
631 + 31473037 = 31473668

Showing the first eight; more decompositions exist.
