Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987486, here are decompositions:

13 + 987473 = 987486
23 + 987463 = 987486
29 + 987457 = 987486
53 + 987433 = 987486
103 + 987383 = 987486
173 + 987313 = 987486
193 + 987293 = 987486
277 + 987209 = 987486

Showing the first eight; more decompositions exist.
