Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40064, here are decompositions:

127 + 39937 = 40064
163 + 39901 = 40064
181 + 39883 = 40064
223 + 39841 = 40064
331 + 39733 = 40064
337 + 39727 = 40064
397 + 39667 = 40064
433 + 39631 = 40064

Showing the first eight; more decompositions exist.
