Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657478, here are decompositions:

17 + 8657461 = 8657478
29 + 8657449 = 8657478
47 + 8657431 = 8657478
97 + 8657381 = 8657478
101 + 8657377 = 8657478
229 + 8657249 = 8657478
239 + 8657239 = 8657478
241 + 8657237 = 8657478

Showing the first eight; more decompositions exist.
