Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981576, here are decompositions:

7 + 981569 = 981576
53 + 981523 = 981576
59 + 981517 = 981576
83 + 981493 = 981576
103 + 981473 = 981576
109 + 981467 = 981576
137 + 981439 = 981576
139 + 981437 = 981576

Showing the first eight; more decompositions exist.
