Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740874, here are decompositions:

3 + 8740871 = 8740874
7 + 8740867 = 8740874
67 + 8740807 = 8740874
193 + 8740681 = 8740874
271 + 8740603 = 8740874
283 + 8740591 = 8740874
313 + 8740561 = 8740874
421 + 8740453 = 8740874

Showing the first eight; more decompositions exist.
