Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712574, here are decompositions:

41 + 8712533 = 8712574
83 + 8712491 = 8712574
251 + 8712323 = 8712574
263 + 8712311 = 8712574
281 + 8712293 = 8712574
293 + 8712281 = 8712574
317 + 8712257 = 8712574
347 + 8712227 = 8712574

Showing the first eight; more decompositions exist.
