Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987662, here are decompositions:

3 + 987659 = 987662
31 + 987631 = 987662
103 + 987559 = 987662
139 + 987523 = 987662
199 + 987463 = 987662
229 + 987433 = 987662
271 + 987391 = 987662
349 + 987313 = 987662

Showing the first eight; more decompositions exist.
