Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990718, here are decompositions:

11 + 990707 = 990718
347 + 990371 = 990718
359 + 990359 = 990718
389 + 990329 = 990718
431 + 990287 = 990718
479 + 990239 = 990718
719 + 989999 = 990718
797 + 989921 = 990718

Showing the first eight; more decompositions exist.
