Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155964, here are decompositions:

43 + 155921 = 155964
71 + 155893 = 155964
73 + 155891 = 155964
101 + 155863 = 155964
103 + 155861 = 155964
113 + 155851 = 155964
131 + 155833 = 155964
163 + 155801 = 155964

Showing the first eight; more decompositions exist.
