Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459526, here are decompositions:

127 + 31459399 = 31459526
139 + 31459387 = 31459526
433 + 31459093 = 31459526
457 + 31459069 = 31459526
463 + 31459063 = 31459526
613 + 31458913 = 31459526
619 + 31458907 = 31459526
727 + 31458799 = 31459526

Showing the first eight; more decompositions exist.
