Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518454, here are decompositions:

7 + 518447 = 518454
23 + 518431 = 518454
37 + 518417 = 518454
43 + 518411 = 518454
67 + 518387 = 518454
113 + 518341 = 518454
127 + 518327 = 518454
163 + 518291 = 518454

Showing the first eight; more decompositions exist.
