Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459574, here are decompositions:

283 + 31459291 = 31459574
313 + 31459261 = 31459574
373 + 31459201 = 31459574
463 + 31459111 = 31459574
607 + 31458967 = 31459574
661 + 31458913 = 31459574
673 + 31458901 = 31459574
787 + 31458787 = 31459574

Showing the first eight; more decompositions exist.
