Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471454, here are decompositions:

43 + 31471411 = 31471454
67 + 31471387 = 31471454
97 + 31471357 = 31471454
241 + 31471213 = 31471454
283 + 31471171 = 31471454
307 + 31471147 = 31471454
331 + 31471123 = 31471454
457 + 31470997 = 31471454

Showing the first eight; more decompositions exist.
