Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732478, here are decompositions:

5 + 8732473 = 8732478
17 + 8732461 = 8732478
31 + 8732447 = 8732478
47 + 8732431 = 8732478
61 + 8732417 = 8732478
67 + 8732411 = 8732478
107 + 8732371 = 8732478
109 + 8732369 = 8732478

Showing the first eight; more decompositions exist.
