Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515996, here are decompositions:

3 + 515993 = 515996
67 + 515929 = 515996
73 + 515923 = 515996
79 + 515917 = 515996
109 + 515887 = 515996
139 + 515857 = 515996
157 + 515839 = 515996
193 + 515803 = 515996

Showing the first eight; more decompositions exist.
