Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156188, here are decompositions:

31 + 156157 = 156188
37 + 156151 = 156188
61 + 156127 = 156188
79 + 156109 = 156188
127 + 156061 = 156188
181 + 156007 = 156188
337 + 155851 = 156188
367 + 155821 = 156188

Showing the first eight; more decompositions exist.
