Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740642, here are decompositions:

83 + 8740559 = 8740642
101 + 8740541 = 8740642
149 + 8740493 = 8740642
269 + 8740373 = 8740642
311 + 8740331 = 8740642
353 + 8740289 = 8740642
479 + 8740163 = 8740642
503 + 8740139 = 8740642

Showing the first eight; more decompositions exist.
