Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152890, here are decompositions:

11 + 152879 = 152890
47 + 152843 = 152890
53 + 152837 = 152890
71 + 152819 = 152890
107 + 152783 = 152890
113 + 152777 = 152890
137 + 152753 = 152890
167 + 152723 = 152890

Showing the first eight; more decompositions exist.
