Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23418, here are decompositions:

19 + 23399 = 23418
47 + 23371 = 23418
61 + 23357 = 23418
79 + 23339 = 23418
97 + 23321 = 23418
107 + 23311 = 23418
127 + 23291 = 23418
139 + 23279 = 23418

Showing the first eight; more decompositions exist.
