Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708742, here are decompositions:

11 + 8708731 = 8708742
41 + 8708701 = 8708742
79 + 8708663 = 8708742
103 + 8708639 = 8708742
131 + 8708611 = 8708742
151 + 8708591 = 8708742
223 + 8708519 = 8708742
233 + 8708509 = 8708742

Showing the first eight; more decompositions exist.
