Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473734, here are decompositions:

31 + 31473703 = 31473734
151 + 31473583 = 31473734
211 + 31473523 = 31473734
277 + 31473457 = 31473734
337 + 31473397 = 31473734
421 + 31473313 = 31473734
547 + 31473187 = 31473734
571 + 31473163 = 31473734

Showing the first eight; more decompositions exist.
