Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470266, here are decompositions:

7 + 31470259 = 31470266
43 + 31470223 = 31470266
67 + 31470199 = 31470266
73 + 31470193 = 31470266
193 + 31470073 = 31470266
199 + 31470067 = 31470266
229 + 31470037 = 31470266
277 + 31469989 = 31470266

Showing the first eight; more decompositions exist.
