Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459652, here are decompositions:

19 + 31459633 = 31459652
31 + 31459621 = 31459652
43 + 31459609 = 31459652
313 + 31459339 = 31459652
331 + 31459321 = 31459652
541 + 31459111 = 31459652
739 + 31458913 = 31459652
751 + 31458901 = 31459652

Showing the first eight; more decompositions exist.
