Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463382, here are decompositions:

19 + 31463363 = 31463382
29 + 31463353 = 31463382
53 + 31463329 = 31463382
61 + 31463321 = 31463382
101 + 31463281 = 31463382
113 + 31463269 = 31463382
179 + 31463203 = 31463382
283 + 31463099 = 31463382

Showing the first eight; more decompositions exist.
