Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574582, here are decompositions:

19 + 31574563 = 31574582
103 + 31574479 = 31574582
139 + 31574443 = 31574582
163 + 31574419 = 31574582
349 + 31574233 = 31574582
379 + 31574203 = 31574582
409 + 31574173 = 31574582
541 + 31574041 = 31574582

Showing the first eight; more decompositions exist.
