Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998942, here are decompositions:

103 + 998839 = 998942
163 + 998779 = 998942
193 + 998749 = 998942
199 + 998743 = 998942
313 + 998629 = 998942
499 + 998443 = 998942
523 + 998419 = 998942
613 + 998329 = 998942

Showing the first eight; more decompositions exist.
