Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500668, here are decompositions:

89 + 500579 = 500668
101 + 500567 = 500668
149 + 500519 = 500668
167 + 500501 = 500668
197 + 500471 = 500668
251 + 500417 = 500668
347 + 500321 = 500668
419 + 500249 = 500668

Showing the first eight; more decompositions exist.
