Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459554, here are decompositions:

13 + 31459541 = 31459554
37 + 31459517 = 31459554
67 + 31459487 = 31459554
97 + 31459457 = 31459554
167 + 31459387 = 31459554
197 + 31459357 = 31459554
211 + 31459343 = 31459554
233 + 31459321 = 31459554

Showing the first eight; more decompositions exist.
