Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513078, here are decompositions:

11 + 513067 = 513078
19 + 513059 = 513078
31 + 513047 = 513078
37 + 513041 = 513078
47 + 513031 = 513078
61 + 513017 = 513078
79 + 512999 = 513078
89 + 512989 = 513078

Showing the first eight; more decompositions exist.
