Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528362, here are decompositions:

13 + 31528349 = 31528362
71 + 31528291 = 31528362
79 + 31528283 = 31528362
83 + 31528279 = 31528362
149 + 31528213 = 31528362
191 + 31528171 = 31528362
193 + 31528169 = 31528362
211 + 31528151 = 31528362

Showing the first eight; more decompositions exist.
