Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990768, here are decompositions:

7 + 990761 = 990768
61 + 990707 = 990768
131 + 990637 = 990768
137 + 990631 = 990768
179 + 990589 = 990768
239 + 990529 = 990768
257 + 990511 = 990768
271 + 990497 = 990768

Showing the first eight; more decompositions exist.
