Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981672, here are decompositions:

19 + 981653 = 981672
71 + 981601 = 981672
73 + 981599 = 981672
103 + 981569 = 981672
149 + 981523 = 981672
179 + 981493 = 981672
191 + 981481 = 981672
199 + 981473 = 981672

Showing the first eight; more decompositions exist.
