Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517990, here are decompositions:

23 + 517967 = 517990
41 + 517949 = 517990
59 + 517931 = 517990
71 + 517919 = 517990
89 + 517901 = 517990
113 + 517877 = 517990
167 + 517823 = 517990
173 + 517817 = 517990

Showing the first eight; more decompositions exist.
