Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981596, here are decompositions:

19 + 981577 = 981596
73 + 981523 = 981596
79 + 981517 = 981596
103 + 981493 = 981596
157 + 981439 = 981596
199 + 981397 = 981596
223 + 981373 = 981596
277 + 981319 = 981596

Showing the first eight; more decompositions exist.
