Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151992, here are decompositions:

23 + 151969 = 151992
53 + 151939 = 151992
83 + 151909 = 151992
89 + 151903 = 151992
109 + 151883 = 151992
151 + 151841 = 151992
179 + 151813 = 151992
193 + 151799 = 151992

Showing the first eight; more decompositions exist.
