Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519206, here are decompositions:

13 + 519193 = 519206
109 + 519097 = 519206
139 + 519067 = 519206
223 + 518983 = 519206
313 + 518893 = 519206
397 + 518809 = 519206
439 + 518767 = 519206
463 + 518743 = 519206

Showing the first eight; more decompositions exist.
