Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712450, here are decompositions:

29 + 8712421 = 8712450
53 + 8712397 = 8712450
79 + 8712371 = 8712450
83 + 8712367 = 8712450
101 + 8712349 = 8712450
113 + 8712337 = 8712450
127 + 8712323 = 8712450
139 + 8712311 = 8712450

Showing the first eight; more decompositions exist.
