Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63998, here are decompositions:

97 + 63901 = 63998
157 + 63841 = 63998
199 + 63799 = 63998
271 + 63727 = 63998
307 + 63691 = 63998
331 + 63667 = 63998
349 + 63649 = 63998
397 + 63601 = 63998

Showing the first eight; more decompositions exist.
