Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470452, here are decompositions:

43 + 31470409 = 31470452
73 + 31470379 = 31470452
193 + 31470259 = 31470452
229 + 31470223 = 31470452
379 + 31470073 = 31470452
439 + 31470013 = 31470452
463 + 31469989 = 31470452
499 + 31469953 = 31470452

Showing the first eight; more decompositions exist.
