Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487378, here are decompositions:

29 + 487349 = 487378
71 + 487307 = 487378
131 + 487247 = 487378
167 + 487211 = 487378
191 + 487187 = 487378
401 + 486977 = 487378
431 + 486947 = 487378
449 + 486929 = 487378

Showing the first eight; more decompositions exist.
