Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708442, here are decompositions:

13 + 8708429 = 8708442
19 + 8708423 = 8708442
31 + 8708411 = 8708442
103 + 8708339 = 8708442
151 + 8708291 = 8708442
173 + 8708269 = 8708442
181 + 8708261 = 8708442
241 + 8708201 = 8708442

Showing the first eight; more decompositions exist.
