Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712428, here are decompositions:

7 + 8712421 = 8712428
31 + 8712397 = 8712428
61 + 8712367 = 8712428
79 + 8712349 = 8712428
199 + 8712229 = 8712428
271 + 8712157 = 8712428
337 + 8712091 = 8712428
409 + 8712019 = 8712428

Showing the first eight; more decompositions exist.
