Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459466, here are decompositions:

67 + 31459399 = 31459466
79 + 31459387 = 31459466
109 + 31459357 = 31459466
127 + 31459339 = 31459466
373 + 31459093 = 31459466
397 + 31459069 = 31459466
499 + 31458967 = 31459466
757 + 31458709 = 31459466

Showing the first eight; more decompositions exist.
