Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156198, here are decompositions:

41 + 156157 = 156198
47 + 156151 = 156198
59 + 156139 = 156198
67 + 156131 = 156198
71 + 156127 = 156198
79 + 156119 = 156198
89 + 156109 = 156198
109 + 156089 = 156198

Showing the first eight; more decompositions exist.
