Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982990, here are decompositions:

17 + 982973 = 982990
23 + 982967 = 982990
59 + 982931 = 982990
149 + 982841 = 982990
293 + 982697 = 982990
347 + 982643 = 982990
401 + 982589 = 982990
419 + 982571 = 982990

Showing the first eight; more decompositions exist.
