Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154962, here are decompositions:

19 + 154943 = 154962
29 + 154933 = 154962
79 + 154883 = 154962
89 + 154873 = 154962
113 + 154849 = 154962
139 + 154823 = 154962
163 + 154799 = 154962
173 + 154789 = 154962

Showing the first eight; more decompositions exist.
