Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732520, here are decompositions:

19 + 8732501 = 8732520
31 + 8732489 = 8732520
47 + 8732473 = 8732520
59 + 8732461 = 8732520
73 + 8732447 = 8732520
89 + 8732431 = 8732520
103 + 8732417 = 8732520
109 + 8732411 = 8732520

Showing the first eight; more decompositions exist.
