Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731888, here are decompositions:

29 + 8731859 = 8731888
71 + 8731817 = 8731888
101 + 8731787 = 8731888
131 + 8731757 = 8731888
167 + 8731721 = 8731888
227 + 8731661 = 8731888
251 + 8731637 = 8731888
281 + 8731607 = 8731888

Showing the first eight; more decompositions exist.
