Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459690, here are decompositions:

11 + 31459679 = 31459690
23 + 31459667 = 31459690
29 + 31459661 = 31459690
71 + 31459619 = 31459690
137 + 31459553 = 31459690
149 + 31459541 = 31459690
173 + 31459517 = 31459690
191 + 31459499 = 31459690

Showing the first eight; more decompositions exist.
