Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515690, here are decompositions:

3 + 515687 = 515690
13 + 515677 = 515690
37 + 515653 = 515690
79 + 515611 = 515690
103 + 515587 = 515690
127 + 515563 = 515690
151 + 515539 = 515690
313 + 515377 = 515690

Showing the first eight; more decompositions exist.
