Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981776, here are decompositions:

7 + 981769 = 981776
73 + 981703 = 981776
79 + 981697 = 981776
139 + 981637 = 981776
199 + 981577 = 981776
283 + 981493 = 981776
337 + 981439 = 981776
379 + 981397 = 981776

Showing the first eight; more decompositions exist.
