Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469582, here are decompositions:

3 + 31469579 = 31469582
13 + 31469569 = 31469582
19 + 31469563 = 31469582
139 + 31469443 = 31469582
229 + 31469353 = 31469582
283 + 31469299 = 31469582
373 + 31469209 = 31469582
439 + 31469143 = 31469582

Showing the first eight; more decompositions exist.
