Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519830, here are decompositions:

13 + 519817 = 519830
37 + 519793 = 519830
43 + 519787 = 519830
61 + 519769 = 519830
97 + 519733 = 519830
127 + 519703 = 519830
139 + 519691 = 519830
163 + 519667 = 519830

Showing the first eight; more decompositions exist.
