Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731926, here are decompositions:

13 + 8731913 = 8731926
19 + 8731907 = 8731926
53 + 8731873 = 8731926
59 + 8731867 = 8731926
67 + 8731859 = 8731926
107 + 8731819 = 8731926
109 + 8731817 = 8731926
139 + 8731787 = 8731926

Showing the first eight; more decompositions exist.
