Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15506, here are decompositions:

13 + 15493 = 15506
67 + 15439 = 15506
79 + 15427 = 15506
157 + 15349 = 15506
193 + 15313 = 15506
199 + 15307 = 15506
229 + 15277 = 15506
307 + 15199 = 15506

Showing the first eight; more decompositions exist.
