Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756478, here are decompositions:

7 + 8756471 = 8756478
19 + 8756459 = 8756478
37 + 8756441 = 8756478
41 + 8756437 = 8756478
97 + 8756381 = 8756478
179 + 8756299 = 8756478
239 + 8756239 = 8756478
257 + 8756221 = 8756478

Showing the first eight; more decompositions exist.
