Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987338, here are decompositions:

127 + 987211 = 987338
139 + 987199 = 987338
211 + 987127 = 987338
241 + 987097 = 987338
271 + 987067 = 987338
277 + 987061 = 987338
349 + 986989 = 987338
379 + 986959 = 987338

Showing the first eight; more decompositions exist.
