Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28136, here are decompositions:

13 + 28123 = 28136
37 + 28099 = 28136
67 + 28069 = 28136
79 + 28057 = 28136
109 + 28027 = 28136
139 + 27997 = 28136
193 + 27943 = 28136
313 + 27823 = 28136

Showing the first eight; more decompositions exist.
