Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731906, here are decompositions:

5 + 8731901 = 8731906
47 + 8731859 = 8731906
89 + 8731817 = 8731906
149 + 8731757 = 8731906
233 + 8731673 = 8731906
263 + 8731643 = 8731906
269 + 8731637 = 8731906
479 + 8731427 = 8731906

Showing the first eight; more decompositions exist.
