Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731790, here are decompositions:

3 + 8731787 = 8731790
7 + 8731783 = 8731790
13 + 8731777 = 8731790
79 + 8731711 = 8731790
103 + 8731687 = 8731790
163 + 8731627 = 8731790
181 + 8731609 = 8731790
211 + 8731579 = 8731790

Showing the first eight; more decompositions exist.
