Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518132, here are decompositions:

3 + 518129 = 518132
19 + 518113 = 518132
31 + 518101 = 518132
73 + 518059 = 518132
151 + 517981 = 518132
271 + 517861 = 518132
421 + 517711 = 518132
523 + 517609 = 518132

Showing the first eight; more decompositions exist.
