Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149202, here are decompositions:

5 + 149197 = 149202
19 + 149183 = 149202
29 + 149173 = 149202
41 + 149161 = 149202
43 + 149159 = 149202
59 + 149143 = 149202
83 + 149119 = 149202
89 + 149113 = 149202

Showing the first eight; more decompositions exist.
