Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513148, here are decompositions:

11 + 513137 = 513148
17 + 513131 = 513148
47 + 513101 = 513148
89 + 513059 = 513148
101 + 513047 = 513148
107 + 513041 = 513148
131 + 513017 = 513148
149 + 512999 = 513148

Showing the first eight; more decompositions exist.
