Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740890, here are decompositions:

19 + 8740871 = 8740890
23 + 8740867 = 8740890
31 + 8740859 = 8740890
83 + 8740807 = 8740890
97 + 8740793 = 8740890
101 + 8740789 = 8740890
107 + 8740783 = 8740890
127 + 8740763 = 8740890

Showing the first eight; more decompositions exist.
