Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987952, here are decompositions:

11 + 987941 = 987952
23 + 987929 = 987952
41 + 987911 = 987952
83 + 987869 = 987952
101 + 987851 = 987952
131 + 987821 = 987952
149 + 987803 = 987952
239 + 987713 = 987952

Showing the first eight; more decompositions exist.
