Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510242, here are decompositions:

43 + 510199 = 510242
163 + 510079 = 510242
181 + 510061 = 510242
193 + 510049 = 510242
211 + 510031 = 510242
283 + 509959 = 510242
331 + 509911 = 510242
379 + 509863 = 510242

Showing the first eight; more decompositions exist.
