Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515772, here are decompositions:

11 + 515761 = 515772
31 + 515741 = 515772
71 + 515701 = 515772
79 + 515693 = 515772
109 + 515663 = 515772
151 + 515621 = 515772
193 + 515579 = 515772
233 + 515539 = 515772

Showing the first eight; more decompositions exist.
