Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729626, here are decompositions:

5 + 8729621 = 8729626
23 + 8729603 = 8729626
83 + 8729543 = 8729626
197 + 8729429 = 8729626
293 + 8729333 = 8729626
317 + 8729309 = 8729626
383 + 8729243 = 8729626
419 + 8729207 = 8729626

Showing the first eight; more decompositions exist.
