Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156030, here are decompositions:

11 + 156019 = 156030
19 + 156011 = 156030
23 + 156007 = 156030
109 + 155921 = 156030
137 + 155893 = 156030
139 + 155891 = 156030
167 + 155863 = 156030
179 + 155851 = 156030

Showing the first eight; more decompositions exist.
