Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518122, here are decompositions:

23 + 518099 = 518122
131 + 517991 = 518122
173 + 517949 = 518122
191 + 517931 = 518122
383 + 517739 = 518122
389 + 517733 = 518122
401 + 517721 = 518122
503 + 517619 = 518122

Showing the first eight; more decompositions exist.
