Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509198, here are decompositions:

61 + 509137 = 509198
97 + 509101 = 509198
127 + 509071 = 509198
211 + 508987 = 509198
229 + 508969 = 509198
241 + 508957 = 509198
331 + 508867 = 509198
409 + 508789 = 509198

Showing the first eight; more decompositions exist.
