Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518368, here are decompositions:

41 + 518327 = 518368
107 + 518261 = 518368
131 + 518237 = 518368
197 + 518171 = 518368
239 + 518129 = 518368
269 + 518099 = 518368
311 + 518057 = 518368
401 + 517967 = 518368

Showing the first eight; more decompositions exist.
