Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459346, here are decompositions:

3 + 31459343 = 31459346
7 + 31459339 = 31459346
223 + 31459123 = 31459346
277 + 31459069 = 31459346
283 + 31459063 = 31459346
379 + 31458967 = 31459346
409 + 31458937 = 31459346
433 + 31458913 = 31459346

Showing the first eight; more decompositions exist.
