Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735638, here are decompositions:

5 + 8735633 = 8735638
17 + 8735621 = 8735638
29 + 8735609 = 8735638
89 + 8735549 = 8735638
101 + 8735537 = 8735638
347 + 8735291 = 8735638
389 + 8735249 = 8735638
599 + 8735039 = 8735638

Showing the first eight; more decompositions exist.
