Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981814, here are decompositions:

3 + 981811 = 981814
5 + 981809 = 981814
17 + 981797 = 981814
83 + 981731 = 981814
101 + 981713 = 981814
107 + 981707 = 981814
131 + 981683 = 981814
191 + 981623 = 981814

Showing the first eight; more decompositions exist.
