Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712672, here are decompositions:

11 + 8712661 = 8712672
43 + 8712629 = 8712672
61 + 8712611 = 8712672
71 + 8712601 = 8712672
139 + 8712533 = 8712672
149 + 8712523 = 8712672
181 + 8712491 = 8712672
251 + 8712421 = 8712672

Showing the first eight; more decompositions exist.
