Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482562, here are decompositions:

3 + 31482559 = 31482562
11 + 31482551 = 31482562
53 + 31482509 = 31482562
173 + 31482389 = 31482562
269 + 31482293 = 31482562
281 + 31482281 = 31482562
383 + 31482179 = 31482562
389 + 31482173 = 31482562

Showing the first eight; more decompositions exist.
