Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731894, here are decompositions:

107 + 8731787 = 8731894
131 + 8731763 = 8731894
137 + 8731757 = 8731894
173 + 8731721 = 8731894
233 + 8731661 = 8731894
251 + 8731643 = 8731894
257 + 8731637 = 8731894
383 + 8731511 = 8731894

Showing the first eight; more decompositions exist.
