Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459504, here are decompositions:

5 + 31459499 = 31459504
17 + 31459487 = 31459504
47 + 31459457 = 31459504
71 + 31459433 = 31459504
281 + 31459223 = 31459504
353 + 31459151 = 31459504
431 + 31459073 = 31459504
521 + 31458983 = 31459504

Showing the first eight; more decompositions exist.
