Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28010, here are decompositions:

13 + 27997 = 28010
43 + 27967 = 28010
67 + 27943 = 28010
109 + 27901 = 28010
127 + 27883 = 28010
163 + 27847 = 28010
193 + 27817 = 28010
211 + 27799 = 28010

Showing the first eight; more decompositions exist.
