Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732870, here are decompositions:

31 + 8732839 = 8732870
37 + 8732833 = 8732870
73 + 8732797 = 8732870
127 + 8732743 = 8732870
151 + 8732719 = 8732870
193 + 8732677 = 8732870
229 + 8732641 = 8732870
271 + 8732599 = 8732870

Showing the first eight; more decompositions exist.
