Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459672, here are decompositions:

5 + 31459667 = 31459672
11 + 31459661 = 31459672
53 + 31459619 = 31459672
131 + 31459541 = 31459672
173 + 31459499 = 31459672
239 + 31459433 = 31459672
263 + 31459409 = 31459672
383 + 31459289 = 31459672

Showing the first eight; more decompositions exist.
