Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741688, here are decompositions:

5 + 8741683 = 8741688
47 + 8741641 = 8741688
79 + 8741609 = 8741688
167 + 8741521 = 8741688
229 + 8741459 = 8741688
251 + 8741437 = 8741688
257 + 8741431 = 8741688
317 + 8741371 = 8741688

Showing the first eight; more decompositions exist.
