Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712620, here are decompositions:

19 + 8712601 = 8712620
43 + 8712577 = 8712620
73 + 8712547 = 8712620
97 + 8712523 = 8712620
199 + 8712421 = 8712620
223 + 8712397 = 8712620
271 + 8712349 = 8712620
283 + 8712337 = 8712620

Showing the first eight; more decompositions exist.
