Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473098, here are decompositions:

31 + 31473067 = 31473098
37 + 31473061 = 31473098
61 + 31473037 = 31473098
67 + 31473031 = 31473098
211 + 31472887 = 31473098
271 + 31472827 = 31473098
487 + 31472611 = 31473098
619 + 31472479 = 31473098

Showing the first eight; more decompositions exist.
