Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731786, here are decompositions:

3 + 8731783 = 8731786
23 + 8731763 = 8731786
29 + 8731757 = 8731786
113 + 8731673 = 8731786
149 + 8731637 = 8731786
179 + 8731607 = 8731786
257 + 8731529 = 8731786
293 + 8731493 = 8731786

Showing the first eight; more decompositions exist.
