Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747406, here are decompositions:

79 + 8747327 = 8747406
149 + 8747257 = 8747406
163 + 8747243 = 8747406
193 + 8747213 = 8747406
313 + 8747093 = 8747406
439 + 8746967 = 8747406
443 + 8746963 = 8747406
449 + 8746957 = 8747406

Showing the first eight; more decompositions exist.
