Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572180, here are decompositions:

3 + 572177 = 572180
19 + 572161 = 572180
43 + 572137 = 572180
73 + 572107 = 572180
127 + 572053 = 572180
139 + 572041 = 572180
157 + 572023 = 572180
211 + 571969 = 572180

Showing the first eight; more decompositions exist.
