Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482718, here are decompositions:

11 + 31482707 = 31482718
101 + 31482617 = 31482718
131 + 31482587 = 31482718
149 + 31482569 = 31482718
167 + 31482551 = 31482718
317 + 31482401 = 31482718
461 + 31482257 = 31482718
599 + 31482119 = 31482718

Showing the first eight; more decompositions exist.
