Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483300, here are decompositions:

71 + 31483229 = 31483300
83 + 31483217 = 31483300
131 + 31483169 = 31483300
137 + 31483163 = 31483300
239 + 31483061 = 31483300
353 + 31482947 = 31483300
461 + 31482839 = 31483300
467 + 31482833 = 31483300

Showing the first eight; more decompositions exist.
