Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459666, here are decompositions:

5 + 31459661 = 31459666
47 + 31459619 = 31459666
113 + 31459553 = 31459666
149 + 31459517 = 31459666
167 + 31459499 = 31459666
179 + 31459487 = 31459666
233 + 31459433 = 31459666
257 + 31459409 = 31459666

Showing the first eight; more decompositions exist.
