Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470468, here are decompositions:

59 + 31470409 = 31470468
89 + 31470379 = 31470468
109 + 31470359 = 31470468
131 + 31470337 = 31470468
251 + 31470217 = 31470468
269 + 31470199 = 31470468
317 + 31470151 = 31470468
401 + 31470067 = 31470468

Showing the first eight; more decompositions exist.
