Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28088, here are decompositions:

7 + 28081 = 28088
19 + 28069 = 28088
31 + 28057 = 28088
37 + 28051 = 28088
61 + 28027 = 28088
127 + 27961 = 28088
241 + 27847 = 28088
271 + 27817 = 28088

Showing the first eight; more decompositions exist.
