Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478160, here are decompositions:

3 + 478157 = 478160
31 + 478129 = 478160
61 + 478099 = 478160
73 + 478087 = 478160
97 + 478063 = 478160
313 + 477847 = 478160
337 + 477823 = 478160
349 + 477811 = 478160

Showing the first eight; more decompositions exist.
