Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987628, here are decompositions:

29 + 987599 = 987628
41 + 987587 = 987628
137 + 987491 = 987628
401 + 987227 = 987628
419 + 987209 = 987628
599 + 987029 = 987628
647 + 986981 = 987628
701 + 986927 = 987628

Showing the first eight; more decompositions exist.
