Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987862, here are decompositions:

11 + 987851 = 987862
41 + 987821 = 987862
53 + 987809 = 987862
59 + 987803 = 987862
149 + 987713 = 987862
263 + 987599 = 987862
269 + 987593 = 987862
353 + 987509 = 987862

Showing the first eight; more decompositions exist.
