Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712918, here are decompositions:

59 + 8712859 = 8712918
139 + 8712779 = 8712918
157 + 8712761 = 8712918
167 + 8712751 = 8712918
191 + 8712727 = 8712918
241 + 8712677 = 8712918
257 + 8712661 = 8712918
307 + 8712611 = 8712918

Showing the first eight; more decompositions exist.
