Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154970, here are decompositions:

37 + 154933 = 154970
43 + 154927 = 154970
73 + 154897 = 154970
97 + 154873 = 154970
163 + 154807 = 154970
181 + 154789 = 154970
223 + 154747 = 154970
271 + 154699 = 154970

Showing the first eight; more decompositions exist.
