Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657078, here are decompositions:

37 + 8657041 = 8657078
61 + 8657017 = 8657078
139 + 8656939 = 8657078
181 + 8656897 = 8657078
229 + 8656849 = 8657078
271 + 8656807 = 8657078
277 + 8656801 = 8657078
349 + 8656729 = 8657078

Showing the first eight; more decompositions exist.
