Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121718, here are decompositions:

7 + 121711 = 121718
31 + 121687 = 121718
97 + 121621 = 121718
109 + 121609 = 121718
127 + 121591 = 121718
139 + 121579 = 121718
211 + 121507 = 121718
271 + 121447 = 121718

Showing the first eight; more decompositions exist.
