Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28046, here are decompositions:

19 + 28027 = 28046
79 + 27967 = 28046
103 + 27943 = 28046
127 + 27919 = 28046
163 + 27883 = 28046
199 + 27847 = 28046
223 + 27823 = 28046
229 + 27817 = 28046

Showing the first eight; more decompositions exist.
