Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28070, here are decompositions:

13 + 28057 = 28070
19 + 28051 = 28070
43 + 28027 = 28070
73 + 27997 = 28070
103 + 27967 = 28070
109 + 27961 = 28070
127 + 27943 = 28070
151 + 27919 = 28070

Showing the first eight; more decompositions exist.
