Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998572, here are decompositions:

11 + 998561 = 998572
59 + 998513 = 998572
101 + 998471 = 998572
149 + 998423 = 998572
173 + 998399 = 998572
191 + 998381 = 998572
353 + 998219 = 998572
359 + 998213 = 998572

Showing the first eight; more decompositions exist.
