Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761836, here are decompositions:

29 + 8761807 = 8761836
47 + 8761789 = 8761836
73 + 8761763 = 8761836
103 + 8761733 = 8761836
197 + 8761639 = 8761836
367 + 8761469 = 8761836
373 + 8761463 = 8761836
379 + 8761457 = 8761836

Showing the first eight; more decompositions exist.
