Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460768, here are decompositions:

67 + 31460701 = 31460768
271 + 31460497 = 31460768
277 + 31460491 = 31460768
337 + 31460431 = 31460768
421 + 31460347 = 31460768
439 + 31460329 = 31460768
487 + 31460281 = 31460768
571 + 31460197 = 31460768

Showing the first eight; more decompositions exist.
