Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712686, here are decompositions:

109 + 8712577 = 8712686
139 + 8712547 = 8712686
163 + 8712523 = 8712686
313 + 8712373 = 8712686
337 + 8712349 = 8712686
349 + 8712337 = 8712686
379 + 8712307 = 8712686
457 + 8712229 = 8712686

Showing the first eight; more decompositions exist.
