Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121098, here are decompositions:

17 + 121081 = 121098
31 + 121067 = 121098
37 + 121061 = 121098
59 + 121039 = 121098
79 + 121019 = 121098
97 + 121001 = 121098
101 + 120997 = 121098
151 + 120947 = 121098

Showing the first eight; more decompositions exist.
