Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708172, here are decompositions:

13 + 8708159 = 8708172
19 + 8708153 = 8708172
29 + 8708143 = 8708172
43 + 8708129 = 8708172
71 + 8708101 = 8708172
79 + 8708093 = 8708172
101 + 8708071 = 8708172
103 + 8708069 = 8708172

Showing the first eight; more decompositions exist.
