Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42806, here are decompositions:

13 + 42793 = 42806
19 + 42787 = 42806
79 + 42727 = 42806
97 + 42709 = 42806
103 + 42703 = 42806
109 + 42697 = 42806
139 + 42667 = 42806
157 + 42649 = 42806

Showing the first eight; more decompositions exist.
