Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513144, here are decompositions:

7 + 513137 = 513144
13 + 513131 = 513144
41 + 513103 = 513144
43 + 513101 = 513144
61 + 513083 = 513144
97 + 513047 = 513144
103 + 513041 = 513144
113 + 513031 = 513144

Showing the first eight; more decompositions exist.
