Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512990, here are decompositions:

13 + 512977 = 512990
31 + 512959 = 512990
61 + 512929 = 512990
73 + 512917 = 512990
193 + 512797 = 512990
211 + 512779 = 512990
223 + 512767 = 512990
229 + 512761 = 512990

Showing the first eight; more decompositions exist.
