Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981594, here are decompositions:

7 + 981587 = 981594
17 + 981577 = 981594
67 + 981527 = 981594
71 + 981523 = 981594
101 + 981493 = 981594
113 + 981481 = 981594
127 + 981467 = 981594
151 + 981443 = 981594

Showing the first eight; more decompositions exist.
