Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712398, here are decompositions:

31 + 8712367 = 8712398
61 + 8712337 = 8712398
139 + 8712259 = 8712398
229 + 8712169 = 8712398
241 + 8712157 = 8712398
307 + 8712091 = 8712398
379 + 8712019 = 8712398
547 + 8711851 = 8712398

Showing the first eight; more decompositions exist.
