Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715740, here are decompositions:

31 + 8715709 = 8715740
37 + 8715703 = 8715740
43 + 8715697 = 8715740
67 + 8715673 = 8715740
73 + 8715667 = 8715740
139 + 8715601 = 8715740
151 + 8715589 = 8715740
181 + 8715559 = 8715740

Showing the first eight; more decompositions exist.
