Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518070, here are decompositions:

11 + 518059 = 518070
13 + 518057 = 518070
23 + 518047 = 518070
53 + 518017 = 518070
71 + 517999 = 518070
79 + 517991 = 518070
89 + 517981 = 518070
103 + 517967 = 518070

Showing the first eight; more decompositions exist.
