Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90630, here are decompositions:

11 + 90619 = 90630
13 + 90617 = 90630
31 + 90599 = 90630
47 + 90583 = 90630
83 + 90547 = 90630
97 + 90533 = 90630
101 + 90529 = 90630
103 + 90527 = 90630

Showing the first eight; more decompositions exist.
