Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459746, here are decompositions:

13 + 31459733 = 31459746
23 + 31459723 = 31459746
29 + 31459717 = 31459746
37 + 31459709 = 31459746
67 + 31459679 = 31459746
79 + 31459667 = 31459746
113 + 31459633 = 31459746
127 + 31459619 = 31459746

Showing the first eight; more decompositions exist.
