Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478148, here are decompositions:

19 + 478129 = 478148
37 + 478111 = 478148
61 + 478087 = 478148
79 + 478069 = 478148
109 + 478039 = 478148
157 + 477991 = 478148
337 + 477811 = 478148
379 + 477769 = 478148

Showing the first eight; more decompositions exist.
