Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990756, here are decompositions:

23 + 990733 = 990756
37 + 990719 = 990756
83 + 990673 = 990756
113 + 990643 = 990756
157 + 990599 = 990756
163 + 990593 = 990756
167 + 990589 = 990756
197 + 990559 = 990756

Showing the first eight; more decompositions exist.
