Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987582, here are decompositions:

23 + 987559 = 987582
41 + 987541 = 987582
59 + 987523 = 987582
73 + 987509 = 987582
109 + 987473 = 987582
149 + 987433 = 987582
191 + 987391 = 987582
199 + 987383 = 987582

Showing the first eight; more decompositions exist.
