Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155070, here are decompositions:

23 + 155047 = 155070
43 + 155027 = 155070
53 + 155017 = 155070
61 + 155009 = 155070
67 + 155003 = 155070
79 + 154991 = 155070
89 + 154981 = 155070
127 + 154943 = 155070

Showing the first eight; more decompositions exist.
