Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731822, here are decompositions:

3 + 8731819 = 8731822
5 + 8731817 = 8731822
59 + 8731763 = 8731822
101 + 8731721 = 8731822
149 + 8731673 = 8731822
179 + 8731643 = 8731822
251 + 8731571 = 8731822
293 + 8731529 = 8731822

Showing the first eight; more decompositions exist.
