Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548700, here are decompositions:

3 + 31548697 = 31548700
23 + 31548677 = 31548700
41 + 31548659 = 31548700
47 + 31548653 = 31548700
59 + 31548641 = 31548700
107 + 31548593 = 31548700
137 + 31548563 = 31548700
149 + 31548551 = 31548700

Showing the first eight; more decompositions exist.
