Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459762, here are decompositions:

3 + 31459759 = 31459762
29 + 31459733 = 31459762
53 + 31459709 = 31459762
83 + 31459679 = 31459762
101 + 31459661 = 31459762
263 + 31459499 = 31459762
353 + 31459409 = 31459762
419 + 31459343 = 31459762

Showing the first eight; more decompositions exist.
