Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731910, here are decompositions:

3 + 8731907 = 8731910
37 + 8731873 = 8731910
43 + 8731867 = 8731910
79 + 8731831 = 8731910
127 + 8731783 = 8731910
199 + 8731711 = 8731910
211 + 8731699 = 8731910
223 + 8731687 = 8731910

Showing the first eight; more decompositions exist.
