Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478154, here are decompositions:

43 + 478111 = 478154
67 + 478087 = 478154
163 + 477991 = 478154
181 + 477973 = 478154
241 + 477913 = 478154
307 + 477847 = 478154
331 + 477823 = 478154
433 + 477721 = 478154

Showing the first eight; more decompositions exist.
