Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459486, here are decompositions:

29 + 31459457 = 31459486
53 + 31459433 = 31459486
137 + 31459349 = 31459486
197 + 31459289 = 31459486
263 + 31459223 = 31459486
269 + 31459217 = 31459486
353 + 31459133 = 31459486
467 + 31459019 = 31459486

Showing the first eight; more decompositions exist.
