Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187098, here are decompositions:

7 + 187091 = 187098
17 + 187081 = 187098
29 + 187069 = 187098
31 + 187067 = 187098
71 + 187027 = 187098
89 + 187009 = 187098
139 + 186959 = 187098
151 + 186947 = 187098

Showing the first eight; more decompositions exist.
