Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528464, here are decompositions:

5 + 31528459 = 31528464
13 + 31528451 = 31528464
17 + 31528447 = 31528464
31 + 31528433 = 31528464
101 + 31528363 = 31528464
127 + 31528337 = 31528464
137 + 31528327 = 31528464
151 + 31528313 = 31528464

Showing the first eight; more decompositions exist.
