Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473110, here are decompositions:

3 + 31473107 = 31473110
43 + 31473067 = 31473110
73 + 31473037 = 31473110
79 + 31473031 = 31473110
127 + 31472983 = 31473110
181 + 31472929 = 31473110
223 + 31472887 = 31473110
271 + 31472839 = 31473110

Showing the first eight; more decompositions exist.
