Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740812, here are decompositions:

5 + 8740807 = 8740812
13 + 8740799 = 8740812
19 + 8740793 = 8740812
23 + 8740789 = 8740812
29 + 8740783 = 8740812
131 + 8740681 = 8740812
163 + 8740649 = 8740812
233 + 8740579 = 8740812

Showing the first eight; more decompositions exist.
