Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998812, here are decompositions:

53 + 998759 = 998812
131 + 998681 = 998812
179 + 998633 = 998812
251 + 998561 = 998812
383 + 998429 = 998812
389 + 998423 = 998812
401 + 998411 = 998812
431 + 998381 = 998812

Showing the first eight; more decompositions exist.
