Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969890, here are decompositions:

13 + 969877 = 969890
127 + 969763 = 969890
211 + 969679 = 969890
223 + 969667 = 969890
331 + 969559 = 969890
409 + 969481 = 969890
433 + 969457 = 969890
457 + 969433 = 969890

Showing the first eight; more decompositions exist.
