Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 546640, here are decompositions:

23 + 546617 = 546640
41 + 546599 = 546640
53 + 546587 = 546640
71 + 546569 = 546640
131 + 546509 = 546640
173 + 546467 = 546640
179 + 546461 = 546640
317 + 546323 = 546640

Showing the first eight; more decompositions exist.
