Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470084, here are decompositions:

11 + 31470073 = 31470084
17 + 31470067 = 31470084
47 + 31470037 = 31470084
71 + 31470013 = 31470084
97 + 31469987 = 31470084
131 + 31469953 = 31470084
181 + 31469903 = 31470084
223 + 31469861 = 31470084

Showing the first eight; more decompositions exist.
