Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518548, here are decompositions:

5 + 518543 = 518548
101 + 518447 = 518548
131 + 518417 = 518548
137 + 518411 = 518548
257 + 518291 = 518548
311 + 518237 = 518548
389 + 518159 = 518548
419 + 518129 = 518548

Showing the first eight; more decompositions exist.
