Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731900, here are decompositions:

41 + 8731859 = 8731900
83 + 8731817 = 8731900
113 + 8731787 = 8731900
137 + 8731763 = 8731900
179 + 8731721 = 8731900
227 + 8731673 = 8731900
239 + 8731661 = 8731900
257 + 8731643 = 8731900

Showing the first eight; more decompositions exist.
