Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987606, here are decompositions:

7 + 987599 = 987606
13 + 987593 = 987606
19 + 987587 = 987606
47 + 987559 = 987606
73 + 987533 = 987606
83 + 987523 = 987606
97 + 987509 = 987606
149 + 987457 = 987606

Showing the first eight; more decompositions exist.
