Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757242, here are decompositions:

19 + 8757223 = 8757242
181 + 8757061 = 8757242
223 + 8757019 = 8757242
229 + 8757013 = 8757242
271 + 8756971 = 8757242
283 + 8756959 = 8757242
619 + 8756623 = 8757242
691 + 8756551 = 8757242

Showing the first eight; more decompositions exist.
