Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512972, here are decompositions:

13 + 512959 = 512972
43 + 512929 = 512972
73 + 512899 = 512972
151 + 512821 = 512972
193 + 512779 = 512972
211 + 512761 = 512972
331 + 512641 = 512972
379 + 512593 = 512972

Showing the first eight; more decompositions exist.
