Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459558, here are decompositions:

5 + 31459553 = 31459558
17 + 31459541 = 31459558
41 + 31459517 = 31459558
59 + 31459499 = 31459558
71 + 31459487 = 31459558
101 + 31459457 = 31459558
149 + 31459409 = 31459558
269 + 31459289 = 31459558

Showing the first eight; more decompositions exist.
