Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519242, here are decompositions:

13 + 519229 = 519242
151 + 519091 = 519242
211 + 519031 = 519242
331 + 518911 = 519242
349 + 518893 = 519242
379 + 518863 = 519242
433 + 518809 = 519242
439 + 518803 = 519242

Showing the first eight; more decompositions exist.
