Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987948, here are decompositions:

7 + 987941 = 987948
19 + 987929 = 987948
37 + 987911 = 987948
79 + 987869 = 987948
97 + 987851 = 987948
127 + 987821 = 987948
139 + 987809 = 987948
151 + 987797 = 987948

Showing the first eight; more decompositions exist.
