Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470050, here are decompositions:

13 + 31470037 = 31470050
37 + 31470013 = 31470050
61 + 31469989 = 31470050
97 + 31469953 = 31470050
127 + 31469923 = 31470050
193 + 31469857 = 31470050
379 + 31469671 = 31470050
397 + 31469653 = 31470050

Showing the first eight; more decompositions exist.
