Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459654, here are decompositions:

3 + 31459651 = 31459654
101 + 31459553 = 31459654
113 + 31459541 = 31459654
137 + 31459517 = 31459654
167 + 31459487 = 31459654
197 + 31459457 = 31459654
311 + 31459343 = 31459654
431 + 31459223 = 31459654

Showing the first eight; more decompositions exist.
