Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731936, here are decompositions:

23 + 8731913 = 8731936
29 + 8731907 = 8731936
149 + 8731787 = 8731936
173 + 8731763 = 8731936
179 + 8731757 = 8731936
263 + 8731673 = 8731936
293 + 8731643 = 8731936
443 + 8731493 = 8731936

Showing the first eight; more decompositions exist.
