Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5418, here are decompositions:

5 + 5413 = 5418
11 + 5407 = 5418
19 + 5399 = 5418
31 + 5387 = 5418
37 + 5381 = 5418
67 + 5351 = 5418
71 + 5347 = 5418
109 + 5309 = 5418

Showing the first eight; more decompositions exist.
