Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115618, here are decompositions:

5 + 115613 = 115618
17 + 115601 = 115618
29 + 115589 = 115618
47 + 115571 = 115618
71 + 115547 = 115618
149 + 115469 = 115618
197 + 115421 = 115618
257 + 115361 = 115618

Showing the first eight; more decompositions exist.
