Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459702, here are decompositions:

5 + 31459697 = 31459702
23 + 31459679 = 31459702
41 + 31459661 = 31459702
83 + 31459619 = 31459702
149 + 31459553 = 31459702
269 + 31459433 = 31459702
293 + 31459409 = 31459702
353 + 31459349 = 31459702

Showing the first eight; more decompositions exist.
