Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981546, here are decompositions:

19 + 981527 = 981546
23 + 981523 = 981546
29 + 981517 = 981546
53 + 981493 = 981546
73 + 981473 = 981546
79 + 981467 = 981546
103 + 981443 = 981546
107 + 981439 = 981546

Showing the first eight; more decompositions exist.
