Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40972, here are decompositions:

11 + 40961 = 40972
23 + 40949 = 40972
89 + 40883 = 40972
131 + 40841 = 40972
149 + 40823 = 40972
233 + 40739 = 40972
263 + 40709 = 40972
389 + 40583 = 40972

Showing the first eight; more decompositions exist.
