Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747426, here are decompositions:

3 + 8747423 = 8747426
7 + 8747419 = 8747426
19 + 8747407 = 8747426
97 + 8747329 = 8747426
307 + 8747119 = 8747426
463 + 8746963 = 8747426
487 + 8746939 = 8747426
547 + 8746879 = 8747426

Showing the first eight; more decompositions exist.
