Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987758, here are decompositions:

19 + 987739 = 987758
61 + 987697 = 987758
127 + 987631 = 987758
151 + 987607 = 987758
199 + 987559 = 987758
367 + 987391 = 987758
397 + 987361 = 987758
547 + 987211 = 987758

Showing the first eight; more decompositions exist.
