Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528834, here are decompositions:

3 + 31528831 = 31528834
11 + 31528823 = 31528834
23 + 31528811 = 31528834
83 + 31528751 = 31528834
137 + 31528697 = 31528834
383 + 31528451 = 31528834
401 + 31528433 = 31528834
461 + 31528373 = 31528834

Showing the first eight; more decompositions exist.
