Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15548, here are decompositions:

7 + 15541 = 15548
37 + 15511 = 15548
97 + 15451 = 15548
109 + 15439 = 15548
157 + 15391 = 15548
199 + 15349 = 15548
229 + 15319 = 15548
241 + 15307 = 15548

Showing the first eight; more decompositions exist.
