Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576376, here are decompositions:

3 + 31576373 = 31576376
109 + 31576267 = 31576376
157 + 31576219 = 31576376
367 + 31576009 = 31576376
373 + 31576003 = 31576376
439 + 31575937 = 31576376
499 + 31575877 = 31576376
547 + 31575829 = 31576376

Showing the first eight; more decompositions exist.
