Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990726, here are decompositions:

7 + 990719 = 990726
19 + 990707 = 990726
53 + 990673 = 990726
83 + 990643 = 990726
89 + 990637 = 990726
127 + 990599 = 990726
137 + 990589 = 990726
167 + 990559 = 990726

Showing the first eight; more decompositions exist.
