Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569752, here are decompositions:

43 + 31569709 = 31569752
61 + 31569691 = 31569752
139 + 31569613 = 31569752
271 + 31569481 = 31569752
373 + 31569379 = 31569752
433 + 31569319 = 31569752
523 + 31569229 = 31569752
601 + 31569151 = 31569752

Showing the first eight; more decompositions exist.
