Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459506, here are decompositions:

7 + 31459499 = 31459506
19 + 31459487 = 31459506
73 + 31459433 = 31459506
97 + 31459409 = 31459506
107 + 31459399 = 31459506
149 + 31459357 = 31459506
157 + 31459349 = 31459506
163 + 31459343 = 31459506

Showing the first eight; more decompositions exist.
