Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585172, here are decompositions:

23 + 585149 = 585172
41 + 585131 = 585172
53 + 585119 = 585172
59 + 585113 = 585172
101 + 585071 = 585172
131 + 585041 = 585172
149 + 585023 = 585172
173 + 584999 = 585172

Showing the first eight; more decompositions exist.
