Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518130, here are decompositions:

7 + 518123 = 518130
17 + 518113 = 518130
29 + 518101 = 518130
31 + 518099 = 518130
47 + 518083 = 518130
71 + 518059 = 518130
73 + 518057 = 518130
83 + 518047 = 518130

Showing the first eight; more decompositions exist.
