Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673874, here are decompositions:

113 + 8673761 = 8673874
191 + 8673683 = 8673874
197 + 8673677 = 8673874
263 + 8673611 = 8673874
281 + 8673593 = 8673874
653 + 8673221 = 8673874
743 + 8673131 = 8673874
761 + 8673113 = 8673874

Showing the first eight; more decompositions exist.
