Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482678, here are decompositions:

11 + 31482667 = 31482678
37 + 31482641 = 31482678
47 + 31482631 = 31482678
61 + 31482617 = 31482678
79 + 31482599 = 31482678
109 + 31482569 = 31482678
127 + 31482551 = 31482678
167 + 31482511 = 31482678

Showing the first eight; more decompositions exist.
