Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13148, here are decompositions:

139 + 13009 = 13148
181 + 12967 = 13148
229 + 12919 = 13148
241 + 12907 = 13148
307 + 12841 = 13148
349 + 12799 = 13148
367 + 12781 = 13148
409 + 12739 = 13148

Showing the first eight; more decompositions exist.
