Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761572, here are decompositions:

41 + 8761531 = 8761572
103 + 8761469 = 8761572
109 + 8761463 = 8761572
139 + 8761433 = 8761572
233 + 8761339 = 8761572
269 + 8761303 = 8761572
283 + 8761289 = 8761572
293 + 8761279 = 8761572

Showing the first eight; more decompositions exist.
