Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459276, here are decompositions:

53 + 31459223 = 31459276
59 + 31459217 = 31459276
257 + 31459019 = 31459276
293 + 31458983 = 31459276
353 + 31458923 = 31459276
479 + 31458797 = 31459276
557 + 31458719 = 31459276
587 + 31458689 = 31459276

Showing the first eight; more decompositions exist.
