Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712740, here are decompositions:

13 + 8712727 = 8712740
31 + 8712709 = 8712740
79 + 8712661 = 8712740
139 + 8712601 = 8712740
163 + 8712577 = 8712740
193 + 8712547 = 8712740
367 + 8712373 = 8712740
373 + 8712367 = 8712740

Showing the first eight; more decompositions exist.
