Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756442, here are decompositions:

5 + 8756437 = 8756442
29 + 8756413 = 8756442
41 + 8756401 = 8756442
61 + 8756381 = 8756442
109 + 8756333 = 8756442
179 + 8756263 = 8756442
229 + 8756213 = 8756442
239 + 8756203 = 8756442

Showing the first eight; more decompositions exist.
