Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459088, here are decompositions:

19 + 31459069 = 31459088
151 + 31458937 = 31459088
181 + 31458907 = 31459088
379 + 31458709 = 31459088
421 + 31458667 = 31459088
457 + 31458631 = 31459088
487 + 31458601 = 31459088
499 + 31458589 = 31459088

Showing the first eight; more decompositions exist.
