Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15278, here are decompositions:

7 + 15271 = 15278
19 + 15259 = 15278
37 + 15241 = 15278
61 + 15217 = 15278
79 + 15199 = 15278
139 + 15139 = 15278
157 + 15121 = 15278
331 + 14947 = 15278

Showing the first eight; more decompositions exist.
