Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528374, here are decompositions:

11 + 31528363 = 31528374
37 + 31528337 = 31528374
47 + 31528327 = 31528374
61 + 31528313 = 31528374
83 + 31528291 = 31528374
107 + 31528267 = 31528374
167 + 31528207 = 31528374
223 + 31528151 = 31528374

Showing the first eight; more decompositions exist.
