Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27884, here are decompositions:

37 + 27847 = 27884
61 + 27823 = 27884
67 + 27817 = 27884
151 + 27733 = 27884
193 + 27691 = 27884
211 + 27673 = 27884
397 + 27487 = 27884
457 + 27427 = 27884

Showing the first eight; more decompositions exist.
