Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731770, here are decompositions:

7 + 8731763 = 8731770
13 + 8731757 = 8731770
59 + 8731711 = 8731770
71 + 8731699 = 8731770
83 + 8731687 = 8731770
97 + 8731673 = 8731770
109 + 8731661 = 8731770
127 + 8731643 = 8731770

Showing the first eight; more decompositions exist.
