Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459046, here are decompositions:

79 + 31458967 = 31459046
109 + 31458937 = 31459046
139 + 31458907 = 31459046
337 + 31458709 = 31459046
349 + 31458697 = 31459046
379 + 31458667 = 31459046
439 + 31458607 = 31459046
457 + 31458589 = 31459046

Showing the first eight; more decompositions exist.
