Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518362, here are decompositions:

71 + 518291 = 518362
101 + 518261 = 518362
113 + 518249 = 518362
191 + 518171 = 518362
233 + 518129 = 518362
239 + 518123 = 518362
263 + 518099 = 518362
431 + 517931 = 518362

Showing the first eight; more decompositions exist.
