Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748078, here are decompositions:

47 + 8748031 = 8748078
61 + 8748017 = 8748078
67 + 8748011 = 8748078
107 + 8747971 = 8748078
137 + 8747941 = 8748078
149 + 8747929 = 8748078
151 + 8747927 = 8748078
271 + 8747807 = 8748078

Showing the first eight; more decompositions exist.
