Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481178, here are decompositions:

7 + 481171 = 481178
31 + 481147 = 481178
37 + 481141 = 481178
127 + 481051 = 481178
157 + 481021 = 481178
199 + 480979 = 481178
211 + 480967 = 481178
241 + 480937 = 481178

Showing the first eight; more decompositions exist.
