Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518580, here are decompositions:

37 + 518543 = 518580
47 + 518533 = 518580
59 + 518521 = 518580
71 + 518509 = 518580
107 + 518473 = 518580
109 + 518471 = 518580
113 + 518467 = 518580
149 + 518431 = 518580

Showing the first eight; more decompositions exist.
