Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731836, here are decompositions:

5 + 8731831 = 8731836
17 + 8731819 = 8731836
19 + 8731817 = 8731836
53 + 8731783 = 8731836
59 + 8731777 = 8731836
73 + 8731763 = 8731836
79 + 8731757 = 8731836
137 + 8731699 = 8731836

Showing the first eight; more decompositions exist.
