Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572172, here are decompositions:

11 + 572161 = 572172
79 + 572093 = 572172
103 + 572069 = 572172
109 + 572063 = 572172
113 + 572059 = 572172
131 + 572041 = 572172
149 + 572023 = 572172
199 + 571973 = 572172

Showing the first eight; more decompositions exist.
