Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28260, here are decompositions:

31 + 28229 = 28260
41 + 28219 = 28260
59 + 28201 = 28260
79 + 28181 = 28260
97 + 28163 = 28260
109 + 28151 = 28260
137 + 28123 = 28260
149 + 28111 = 28260

Showing the first eight; more decompositions exist.
