Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470606, here are decompositions:

43 + 31470563 = 31470606
59 + 31470547 = 31470606
137 + 31470469 = 31470606
163 + 31470443 = 31470606
197 + 31470409 = 31470606
227 + 31470379 = 31470606
269 + 31470337 = 31470606
283 + 31470323 = 31470606

Showing the first eight; more decompositions exist.
