Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528366, here are decompositions:

3 + 31528363 = 31528366
17 + 31528349 = 31528366
29 + 31528337 = 31528366
53 + 31528313 = 31528366
83 + 31528283 = 31528366
137 + 31528229 = 31528366
197 + 31528169 = 31528366
239 + 31528127 = 31528366

Showing the first eight; more decompositions exist.
