Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987926, here are decompositions:

13 + 987913 = 987926
229 + 987697 = 987926
367 + 987559 = 987926
463 + 987463 = 987926
613 + 987313 = 987926
727 + 987199 = 987926
733 + 987193 = 987926
829 + 987097 = 987926

Showing the first eight; more decompositions exist.
