Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478162, here are decompositions:

5 + 478157 = 478162
23 + 478139 = 478162
263 + 477899 = 478162
281 + 477881 = 478162
353 + 477809 = 478162
431 + 477731 = 478162
491 + 477671 = 478162
569 + 477593 = 478162

Showing the first eight; more decompositions exist.
