Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459624, here are decompositions:

3 + 31459621 = 31459624
5 + 31459619 = 31459624
71 + 31459553 = 31459624
83 + 31459541 = 31459624
107 + 31459517 = 31459624
137 + 31459487 = 31459624
167 + 31459457 = 31459624
191 + 31459433 = 31459624

Showing the first eight; more decompositions exist.
