Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459498, here are decompositions:

11 + 31459487 = 31459498
41 + 31459457 = 31459498
89 + 31459409 = 31459498
149 + 31459349 = 31459498
281 + 31459217 = 31459498
347 + 31459151 = 31459498
467 + 31459031 = 31459498
479 + 31459019 = 31459498

Showing the first eight; more decompositions exist.
