Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459644, here are decompositions:

11 + 31459633 = 31459644
23 + 31459621 = 31459644
103 + 31459541 = 31459644
127 + 31459517 = 31459644
157 + 31459487 = 31459644
211 + 31459433 = 31459644
257 + 31459387 = 31459644
353 + 31459291 = 31459644

Showing the first eight; more decompositions exist.
