Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459804, here are decompositions:

71 + 31459733 = 31459804
107 + 31459697 = 31459804
137 + 31459667 = 31459804
251 + 31459553 = 31459804
263 + 31459541 = 31459804
317 + 31459487 = 31459804
347 + 31459457 = 31459804
461 + 31459343 = 31459804

Showing the first eight; more decompositions exist.
