Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951990, here are decompositions:

23 + 951967 = 951990
31 + 951959 = 951990
47 + 951943 = 951990
79 + 951911 = 951990
97 + 951893 = 951990
103 + 951887 = 951990
131 + 951859 = 951990
139 + 951851 = 951990

Showing the first eight; more decompositions exist.
