Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459414, here are decompositions:

5 + 31459409 = 31459414
71 + 31459343 = 31459414
191 + 31459223 = 31459414
197 + 31459217 = 31459414
263 + 31459151 = 31459414
281 + 31459133 = 31459414
383 + 31459031 = 31459414
431 + 31458983 = 31459414

Showing the first eight; more decompositions exist.
