Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459660, here are decompositions:

41 + 31459619 = 31459660
107 + 31459553 = 31459660
173 + 31459487 = 31459660
227 + 31459433 = 31459660
251 + 31459409 = 31459660
311 + 31459349 = 31459660
317 + 31459343 = 31459660
443 + 31459217 = 31459660

Showing the first eight; more decompositions exist.
