Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527818, here are decompositions:

29 + 527789 = 527818
89 + 527729 = 527818
191 + 527627 = 527818
227 + 527591 = 527818
311 + 527507 = 527818
419 + 527399 = 527818
491 + 527327 = 527818
659 + 527159 = 527818

Showing the first eight; more decompositions exist.
