Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483312, here are decompositions:

5 + 31483307 = 31483312
83 + 31483229 = 31483312
149 + 31483163 = 31483312
251 + 31483061 = 31483312
479 + 31482833 = 31483312
491 + 31482821 = 31483312
569 + 31482743 = 31483312
743 + 31482569 = 31483312

Showing the first eight; more decompositions exist.
