Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987394, here are decompositions:

3 + 987391 = 987394
11 + 987383 = 987394
41 + 987353 = 987394
101 + 987293 = 987394
167 + 987227 = 987394
251 + 987143 = 987394
293 + 987101 = 987394
311 + 987083 = 987394

Showing the first eight; more decompositions exist.
