Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518374, here are decompositions:

47 + 518327 = 518374
83 + 518291 = 518374
113 + 518261 = 518374
137 + 518237 = 518374
167 + 518207 = 518374
251 + 518123 = 518374
317 + 518057 = 518374
383 + 517991 = 518374

Showing the first eight; more decompositions exist.
