Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519982, here are decompositions:

11 + 519971 = 519982
59 + 519923 = 519982
101 + 519881 = 519982
179 + 519803 = 519982
269 + 519713 = 519982
401 + 519581 = 519982
431 + 519551 = 519982
443 + 519539 = 519982

Showing the first eight; more decompositions exist.
