Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758442, here are decompositions:

13 + 8758429 = 8758442
103 + 8758339 = 8758442
109 + 8758333 = 8758442
163 + 8758279 = 8758442
223 + 8758219 = 8758442
241 + 8758201 = 8758442
271 + 8758171 = 8758442
313 + 8758129 = 8758442

Showing the first eight; more decompositions exist.
