Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731966, here are decompositions:

29 + 8731937 = 8731966
53 + 8731913 = 8731966
59 + 8731907 = 8731966
107 + 8731859 = 8731966
149 + 8731817 = 8731966
179 + 8731787 = 8731966
293 + 8731673 = 8731966
359 + 8731607 = 8731966

Showing the first eight; more decompositions exist.
