Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 975990, here are decompositions:

13 + 975977 = 975990
23 + 975967 = 975990
47 + 975943 = 975990
83 + 975907 = 975990
89 + 975901 = 975990
107 + 975883 = 975990
163 + 975827 = 975990
167 + 975823 = 975990

Showing the first eight; more decompositions exist.
