Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981798, here are decompositions:

29 + 981769 = 981798
67 + 981731 = 981798
101 + 981697 = 981798
107 + 981691 = 981798
197 + 981601 = 981798
199 + 981599 = 981798
211 + 981587 = 981798
229 + 981569 = 981798

Showing the first eight; more decompositions exist.
