Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508582, here are decompositions:

3 + 31508579 = 31508582
13 + 31508569 = 31508582
73 + 31508509 = 31508582
139 + 31508443 = 31508582
223 + 31508359 = 31508582
271 + 31508311 = 31508582
349 + 31508233 = 31508582
379 + 31508203 = 31508582

Showing the first eight; more decompositions exist.
