Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576316, here are decompositions:

97 + 31576219 = 31576316
199 + 31576117 = 31576316
229 + 31576087 = 31576316
307 + 31576009 = 31576316
313 + 31576003 = 31576316
379 + 31575937 = 31576316
439 + 31575877 = 31576316
487 + 31575829 = 31576316

Showing the first eight; more decompositions exist.
