Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156992, here are decompositions:

13 + 156979 = 156992
79 + 156913 = 156992
151 + 156841 = 156992
193 + 156799 = 156992
211 + 156781 = 156992
313 + 156679 = 156992
373 + 156619 = 156992
499 + 156493 = 156992

Showing the first eight; more decompositions exist.
