Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981844, here are decompositions:

47 + 981797 = 981844
113 + 981731 = 981844
131 + 981713 = 981844
137 + 981707 = 981844
191 + 981653 = 981844
257 + 981587 = 981844
317 + 981527 = 981844
401 + 981443 = 981844

Showing the first eight; more decompositions exist.
