Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709742, here are decompositions:

5 + 8709737 = 8709742
11 + 8709731 = 8709742
23 + 8709719 = 8709742
29 + 8709713 = 8709742
89 + 8709653 = 8709742
131 + 8709611 = 8709742
179 + 8709563 = 8709742
233 + 8709509 = 8709742

Showing the first eight; more decompositions exist.
