Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736920, here are decompositions:

13 + 8736907 = 8736920
37 + 8736883 = 8736920
67 + 8736853 = 8736920
103 + 8736817 = 8736920
139 + 8736781 = 8736920
193 + 8736727 = 8736920
337 + 8736583 = 8736920
373 + 8736547 = 8736920

Showing the first eight; more decompositions exist.
