Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175822, here are decompositions:

11 + 175811 = 175822
41 + 175781 = 175822
113 + 175709 = 175822
131 + 175691 = 175822
149 + 175673 = 175822
173 + 175649 = 175822
191 + 175631 = 175822
359 + 175463 = 175822

Showing the first eight; more decompositions exist.
