Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548020, here are decompositions:

3 + 31548017 = 31548020
13 + 31548007 = 31548020
61 + 31547959 = 31548020
67 + 31547953 = 31548020
103 + 31547917 = 31548020
181 + 31547839 = 31548020
271 + 31547749 = 31548020
313 + 31547707 = 31548020

Showing the first eight; more decompositions exist.
