Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534380, here are decompositions:

11 + 31534369 = 31534380
37 + 31534343 = 31534380
47 + 31534333 = 31534380
79 + 31534301 = 31534380
83 + 31534297 = 31534380
109 + 31534271 = 31534380
139 + 31534241 = 31534380
149 + 31534231 = 31534380

Showing the first eight; more decompositions exist.
