Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981654, here are decompositions:

17 + 981637 = 981654
31 + 981623 = 981654
53 + 981601 = 981654
67 + 981587 = 981654
127 + 981527 = 981654
131 + 981523 = 981654
137 + 981517 = 981654
173 + 981481 = 981654

Showing the first eight; more decompositions exist.
