Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470090, here are decompositions:

17 + 31470073 = 31470090
23 + 31470067 = 31470090
53 + 31470037 = 31470090
101 + 31469989 = 31470090
103 + 31469987 = 31470090
137 + 31469953 = 31470090
167 + 31469923 = 31470090
229 + 31469861 = 31470090

Showing the first eight; more decompositions exist.
