Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519158, here are decompositions:

7 + 519151 = 519158
37 + 519121 = 519158
61 + 519097 = 519158
67 + 519091 = 519158
127 + 519031 = 519158
349 + 518809 = 519158
379 + 518779 = 519158
397 + 518761 = 519158

Showing the first eight; more decompositions exist.
