Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987734, here are decompositions:

37 + 987697 = 987734
103 + 987631 = 987734
127 + 987607 = 987734
193 + 987541 = 987734
211 + 987523 = 987734
271 + 987463 = 987734
277 + 987457 = 987734
373 + 987361 = 987734

Showing the first eight; more decompositions exist.
