Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712078, here are decompositions:

19 + 8712059 = 8712078
59 + 8712019 = 8712078
61 + 8712017 = 8712078
107 + 8711971 = 8712078
127 + 8711951 = 8712078
157 + 8711921 = 8712078
181 + 8711897 = 8712078
191 + 8711887 = 8712078

Showing the first eight; more decompositions exist.
