Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175990, here are decompositions:

11 + 175979 = 175990
29 + 175961 = 175990
41 + 175949 = 175990
53 + 175937 = 175990
71 + 175919 = 175990
131 + 175859 = 175990
137 + 175853 = 175990
179 + 175811 = 175990

Showing the first eight; more decompositions exist.
