Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515750, here are decompositions:

13 + 515737 = 515750
73 + 515677 = 515750
97 + 515653 = 515750
139 + 515611 = 515750
163 + 515587 = 515750
211 + 515539 = 515750
349 + 515401 = 515750
373 + 515377 = 515750

Showing the first eight; more decompositions exist.
