Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731964, here are decompositions:

13 + 8731951 = 8731964
97 + 8731867 = 8731964
103 + 8731861 = 8731964
181 + 8731783 = 8731964
277 + 8731687 = 8731964
337 + 8731627 = 8731964
433 + 8731531 = 8731964
463 + 8731501 = 8731964

Showing the first eight; more decompositions exist.
