Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747446, here are decompositions:

5 + 8747441 = 8747446
23 + 8747423 = 8747446
173 + 8747273 = 8747446
233 + 8747213 = 8747446
353 + 8747093 = 8747446
467 + 8746979 = 8747446
479 + 8746967 = 8747446
509 + 8746937 = 8747446

Showing the first eight; more decompositions exist.
