Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470186, here are decompositions:

19 + 31470167 = 31470186
43 + 31470143 = 31470186
89 + 31470097 = 31470186
113 + 31470073 = 31470186
149 + 31470037 = 31470186
173 + 31470013 = 31470186
197 + 31469989 = 31470186
199 + 31469987 = 31470186

Showing the first eight; more decompositions exist.
