Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518626, here are decompositions:

5 + 518621 = 518626
29 + 518597 = 518626
47 + 518579 = 518626
83 + 518543 = 518626
179 + 518447 = 518626
197 + 518429 = 518626
239 + 518387 = 518626
389 + 518237 = 518626

Showing the first eight; more decompositions exist.
