Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747472, here are decompositions:

31 + 8747441 = 8747472
53 + 8747419 = 8747472
199 + 8747273 = 8747472
211 + 8747261 = 8747472
229 + 8747243 = 8747472
281 + 8747191 = 8747472
313 + 8747159 = 8747472
353 + 8747119 = 8747472

Showing the first eight; more decompositions exist.
