Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470536, here are decompositions:

67 + 31470469 = 31470536
127 + 31470409 = 31470536
157 + 31470379 = 31470536
199 + 31470337 = 31470536
277 + 31470259 = 31470536
313 + 31470223 = 31470536
337 + 31470199 = 31470536
439 + 31470097 = 31470536

Showing the first eight; more decompositions exist.
