Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482766, here are decompositions:

5 + 31482761 = 31482766
23 + 31482743 = 31482766
59 + 31482707 = 31482766
83 + 31482683 = 31482766
149 + 31482617 = 31482766
167 + 31482599 = 31482766
179 + 31482587 = 31482766
197 + 31482569 = 31482766

Showing the first eight; more decompositions exist.
