Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175818, here are decompositions:

7 + 175811 = 175818
37 + 175781 = 175818
59 + 175759 = 175818
61 + 175757 = 175818
109 + 175709 = 175818
127 + 175691 = 175818
131 + 175687 = 175818
197 + 175621 = 175818

Showing the first eight; more decompositions exist.
