Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79906, here are decompositions:

3 + 79903 = 79906
5 + 79901 = 79906
17 + 79889 = 79906
59 + 79847 = 79906
83 + 79823 = 79906
89 + 79817 = 79906
137 + 79769 = 79906
149 + 79757 = 79906

Showing the first eight; more decompositions exist.
