Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153144, here are decompositions:

7 + 153137 = 153144
11 + 153133 = 153144
31 + 153113 = 153144
37 + 153107 = 153144
67 + 153077 = 153144
71 + 153073 = 153144
73 + 153071 = 153144
151 + 152993 = 153144

Showing the first eight; more decompositions exist.
