Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528396, here are decompositions:

23 + 31528373 = 31528396
47 + 31528349 = 31528396
59 + 31528337 = 31528396
83 + 31528313 = 31528396
113 + 31528283 = 31528396
167 + 31528229 = 31528396
227 + 31528169 = 31528396
239 + 31528157 = 31528396

Showing the first eight; more decompositions exist.
