Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518654, here are decompositions:

43 + 518611 = 518654
67 + 518587 = 518654
181 + 518473 = 518654
223 + 518431 = 518654
313 + 518341 = 518654
421 + 518233 = 518654
463 + 518191 = 518654
523 + 518131 = 518654

Showing the first eight; more decompositions exist.
