Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705742, here are decompositions:

13 + 8705729 = 8705742
53 + 8705689 = 8705742
61 + 8705681 = 8705742
103 + 8705639 = 8705742
131 + 8705611 = 8705742
181 + 8705561 = 8705742
191 + 8705551 = 8705742
193 + 8705549 = 8705742

Showing the first eight; more decompositions exist.
