Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459754, here are decompositions:

31 + 31459723 = 31459754
37 + 31459717 = 31459754
103 + 31459651 = 31459754
367 + 31459387 = 31459754
397 + 31459357 = 31459754
433 + 31459321 = 31459754
463 + 31459291 = 31459754
631 + 31459123 = 31459754

Showing the first eight; more decompositions exist.
