Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998586, here are decompositions:

47 + 998539 = 998586
59 + 998527 = 998586
73 + 998513 = 998586
89 + 998497 = 998586
157 + 998429 = 998586
163 + 998423 = 998586
167 + 998419 = 998586
233 + 998353 = 998586

Showing the first eight; more decompositions exist.
