Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513130, here are decompositions:

29 + 513101 = 513130
47 + 513083 = 513130
71 + 513059 = 513130
83 + 513047 = 513130
89 + 513041 = 513130
113 + 513017 = 513130
131 + 512999 = 513130
227 + 512903 = 513130

Showing the first eight; more decompositions exist.
