Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990766, here are decompositions:

5 + 990761 = 990766
47 + 990719 = 990766
59 + 990707 = 990766
167 + 990599 = 990766
173 + 990593 = 990766
263 + 990503 = 990766
269 + 990497 = 990766
383 + 990383 = 990766

Showing the first eight; more decompositions exist.
