Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459548, here are decompositions:

7 + 31459541 = 31459548
31 + 31459517 = 31459548
61 + 31459487 = 31459548
139 + 31459409 = 31459548
149 + 31459399 = 31459548
191 + 31459357 = 31459548
199 + 31459349 = 31459548
227 + 31459321 = 31459548

Showing the first eight; more decompositions exist.
