Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473068, here are decompositions:

7 + 31473061 = 31473068
31 + 31473037 = 31473068
37 + 31473031 = 31473068
139 + 31472929 = 31473068
181 + 31472887 = 31473068
229 + 31472839 = 31473068
241 + 31472827 = 31473068
457 + 31472611 = 31473068

Showing the first eight; more decompositions exist.
