Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990886, here are decompositions:

5 + 990881 = 990886
89 + 990797 = 990886
167 + 990719 = 990886
179 + 990707 = 990886
293 + 990593 = 990886
383 + 990503 = 990886
389 + 990497 = 990886
503 + 990383 = 990886

Showing the first eight; more decompositions exist.
