Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990968, here are decompositions:

7 + 990961 = 990968
79 + 990889 = 990968
127 + 990841 = 990968
331 + 990637 = 990968
337 + 990631 = 990968
379 + 990589 = 990968
409 + 990559 = 990968
421 + 990547 = 990968

Showing the first eight; more decompositions exist.
