Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459758, here are decompositions:

41 + 31459717 = 31459758
61 + 31459697 = 31459758
79 + 31459679 = 31459758
97 + 31459661 = 31459758
107 + 31459651 = 31459758
137 + 31459621 = 31459758
139 + 31459619 = 31459758
149 + 31459609 = 31459758

Showing the first eight; more decompositions exist.
