Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459454, here are decompositions:

67 + 31459387 = 31459454
97 + 31459357 = 31459454
163 + 31459291 = 31459454
193 + 31459261 = 31459454
331 + 31459123 = 31459454
487 + 31458967 = 31459454
541 + 31458913 = 31459454
547 + 31458907 = 31459454

Showing the first eight; more decompositions exist.
