Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731916, here are decompositions:

3 + 8731913 = 8731916
43 + 8731873 = 8731916
97 + 8731819 = 8731916
139 + 8731777 = 8731916
229 + 8731687 = 8731916
307 + 8731609 = 8731916
337 + 8731579 = 8731916
439 + 8731477 = 8731916

Showing the first eight; more decompositions exist.
