Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459444, here are decompositions:

11 + 31459433 = 31459444
101 + 31459343 = 31459444
227 + 31459217 = 31459444
293 + 31459151 = 31459444
311 + 31459133 = 31459444
461 + 31458983 = 31459444
491 + 31458953 = 31459444
521 + 31458923 = 31459444

Showing the first eight; more decompositions exist.
