Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990764, here are decompositions:

3 + 990761 = 990764
31 + 990733 = 990764
127 + 990637 = 990764
241 + 990523 = 990764
277 + 990487 = 990764
367 + 990397 = 990764
433 + 990331 = 990764
457 + 990307 = 990764

Showing the first eight; more decompositions exist.
