Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517972, here are decompositions:

5 + 517967 = 517972
23 + 517949 = 517972
41 + 517931 = 517972
53 + 517919 = 517972
71 + 517901 = 517972
149 + 517823 = 517972
233 + 517739 = 517972
239 + 517733 = 517972

Showing the first eight; more decompositions exist.
