Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747726, here are decompositions:

3 + 8747723 = 8747726
37 + 8747689 = 8747726
73 + 8747653 = 8747726
103 + 8747623 = 8747726
109 + 8747617 = 8747726
199 + 8747527 = 8747726
307 + 8747419 = 8747726
397 + 8747329 = 8747726

Showing the first eight; more decompositions exist.
