Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559852, here are decompositions:

3 + 31559849 = 31559852
19 + 31559833 = 31559852
31 + 31559821 = 31559852
43 + 31559809 = 31559852
193 + 31559659 = 31559852
199 + 31559653 = 31559852
211 + 31559641 = 31559852
229 + 31559623 = 31559852

Showing the first eight; more decompositions exist.
