Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459534, here are decompositions:

17 + 31459517 = 31459534
47 + 31459487 = 31459534
101 + 31459433 = 31459534
191 + 31459343 = 31459534
311 + 31459223 = 31459534
317 + 31459217 = 31459534
383 + 31459151 = 31459534
401 + 31459133 = 31459534

Showing the first eight; more decompositions exist.
