Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518544, here are decompositions:

11 + 518533 = 518544
23 + 518521 = 518544
71 + 518473 = 518544
73 + 518471 = 518544
97 + 518447 = 518544
113 + 518431 = 518544
127 + 518417 = 518544
157 + 518387 = 518544

Showing the first eight; more decompositions exist.
