Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15318, here are decompositions:

5 + 15313 = 15318
11 + 15307 = 15318
19 + 15299 = 15318
29 + 15289 = 15318
31 + 15287 = 15318
41 + 15277 = 15318
47 + 15271 = 15318
59 + 15259 = 15318

Showing the first eight; more decompositions exist.
