Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731804, here are decompositions:

17 + 8731787 = 8731804
41 + 8731763 = 8731804
47 + 8731757 = 8731804
83 + 8731721 = 8731804
131 + 8731673 = 8731804
167 + 8731637 = 8731804
197 + 8731607 = 8731804
233 + 8731571 = 8731804

Showing the first eight; more decompositions exist.
