Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513156, here are decompositions:

19 + 513137 = 513156
47 + 513109 = 513156
53 + 513103 = 513156
73 + 513083 = 513156
89 + 513067 = 513156
97 + 513059 = 513156
103 + 513053 = 513156
109 + 513047 = 513156

Showing the first eight; more decompositions exist.
