Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998678, here are decompositions:

61 + 998617 = 998678
127 + 998551 = 998678
139 + 998539 = 998678
151 + 998527 = 998678
181 + 998497 = 998678
349 + 998329 = 998678
367 + 998311 = 998678
397 + 998281 = 998678

Showing the first eight; more decompositions exist.
