Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740256, here are decompositions:

37 + 8740219 = 8740256
73 + 8740183 = 8740256
127 + 8740129 = 8740256
139 + 8740117 = 8740256
337 + 8739919 = 8740256
373 + 8739883 = 8740256
379 + 8739877 = 8740256
433 + 8739823 = 8740256

Showing the first eight; more decompositions exist.
