Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479578, here are decompositions:

17 + 479561 = 479578
89 + 479489 = 479578
137 + 479441 = 479578
149 + 479429 = 479578
191 + 479387 = 479578
251 + 479327 = 479578
269 + 479309 = 479578
311 + 479267 = 479578

Showing the first eight; more decompositions exist.
