Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483342, here are decompositions:

29 + 31483313 = 31483342
113 + 31483229 = 31483342
173 + 31483169 = 31483342
179 + 31483163 = 31483342
281 + 31483061 = 31483342
503 + 31482839 = 31483342
509 + 31482833 = 31483342
521 + 31482821 = 31483342

Showing the first eight; more decompositions exist.
