Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981446, here are decompositions:

3 + 981443 = 981446
7 + 981439 = 981446
73 + 981373 = 981446
127 + 981319 = 981446
157 + 981289 = 981446
163 + 981283 = 981446
307 + 981139 = 981446
313 + 981133 = 981446

Showing the first eight; more decompositions exist.
