Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987814, here are decompositions:

5 + 987809 = 987814
11 + 987803 = 987814
17 + 987797 = 987814
101 + 987713 = 987814
227 + 987587 = 987814
281 + 987533 = 987814
431 + 987383 = 987814
461 + 987353 = 987814

Showing the first eight; more decompositions exist.
