Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576824, here are decompositions:

47 + 31576777 = 31576824
73 + 31576751 = 31576824
151 + 31576673 = 31576824
241 + 31576583 = 31576824
283 + 31576541 = 31576824
313 + 31576511 = 31576824
347 + 31576477 = 31576824
397 + 31576427 = 31576824

Showing the first eight; more decompositions exist.
