Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732742, here are decompositions:

23 + 8732719 = 8732742
89 + 8732653 = 8732742
101 + 8732641 = 8732742
103 + 8732639 = 8732742
149 + 8732593 = 8732742
191 + 8732551 = 8732742
241 + 8732501 = 8732742
269 + 8732473 = 8732742

Showing the first eight; more decompositions exist.
