Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990626, here are decompositions:

37 + 990589 = 990626
67 + 990559 = 990626
79 + 990547 = 990626
97 + 990529 = 990626
103 + 990523 = 990626
139 + 990487 = 990626
157 + 990469 = 990626
163 + 990463 = 990626

Showing the first eight; more decompositions exist.
