Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158202, here are decompositions:

13 + 158189 = 158202
41 + 158161 = 158202
59 + 158143 = 158202
61 + 158141 = 158202
73 + 158129 = 158202
89 + 158113 = 158202
131 + 158071 = 158202
173 + 158029 = 158202

Showing the first eight; more decompositions exist.
