Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528462, here are decompositions:

3 + 31528459 = 31528462
11 + 31528451 = 31528462
29 + 31528433 = 31528462
89 + 31528373 = 31528462
113 + 31528349 = 31528462
149 + 31528313 = 31528462
179 + 31528283 = 31528462
233 + 31528229 = 31528462

Showing the first eight; more decompositions exist.
