Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708142, here are decompositions:

13 + 8708129 = 8708142
41 + 8708101 = 8708142
61 + 8708081 = 8708142
71 + 8708071 = 8708142
73 + 8708069 = 8708142
103 + 8708039 = 8708142
139 + 8708003 = 8708142
173 + 8707969 = 8708142

Showing the first eight; more decompositions exist.
