Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731924, here are decompositions:

11 + 8731913 = 8731924
17 + 8731907 = 8731924
23 + 8731901 = 8731924
107 + 8731817 = 8731924
137 + 8731787 = 8731924
167 + 8731757 = 8731924
251 + 8731673 = 8731924
263 + 8731661 = 8731924

Showing the first eight; more decompositions exist.
