Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756642, here are decompositions:

19 + 8756623 = 8756642
109 + 8756533 = 8756642
229 + 8756413 = 8756642
241 + 8756401 = 8756642
379 + 8756263 = 8756642
409 + 8756233 = 8756642
421 + 8756221 = 8756642
439 + 8756203 = 8756642

Showing the first eight; more decompositions exist.
