Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987968, here are decompositions:

229 + 987739 = 987968
271 + 987697 = 987968
337 + 987631 = 987968
409 + 987559 = 987968
577 + 987391 = 987968
607 + 987361 = 987968
757 + 987211 = 987968
769 + 987199 = 987968

Showing the first eight; more decompositions exist.
