Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459706, here are decompositions:

73 + 31459633 = 31459706
97 + 31459609 = 31459706
307 + 31459399 = 31459706
349 + 31459357 = 31459706
367 + 31459339 = 31459706
613 + 31459093 = 31459706
643 + 31459063 = 31459706
739 + 31458967 = 31459706

Showing the first eight; more decompositions exist.
