Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518508, here are decompositions:

37 + 518471 = 518508
41 + 518467 = 518508
61 + 518447 = 518508
79 + 518429 = 518508
97 + 518411 = 518508
167 + 518341 = 518508
181 + 518327 = 518508
197 + 518311 = 518508

Showing the first eight; more decompositions exist.
