Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576924, here are decompositions:

23 + 31576901 = 31576924
173 + 31576751 = 31576924
251 + 31576673 = 31576924
383 + 31576541 = 31576924
521 + 31576403 = 31576924
557 + 31576367 = 31576924
641 + 31576283 = 31576924
683 + 31576241 = 31576924

Showing the first eight; more decompositions exist.
