Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118242, here are decompositions:

23 + 118219 = 118242
29 + 118213 = 118242
31 + 118211 = 118242
53 + 118189 = 118242
71 + 118171 = 118242
73 + 118169 = 118242
79 + 118163 = 118242
149 + 118093 = 118242

Showing the first eight; more decompositions exist.
