Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987506, here are decompositions:

43 + 987463 = 987506
73 + 987433 = 987506
193 + 987313 = 987506
307 + 987199 = 987506
313 + 987193 = 987506
379 + 987127 = 987506
409 + 987097 = 987506
439 + 987067 = 987506

Showing the first eight; more decompositions exist.
