Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105132, here are decompositions:

61 + 105071 = 105132
101 + 105031 = 105132
109 + 105023 = 105132
113 + 105019 = 105132
173 + 104959 = 105132
179 + 104953 = 105132
199 + 104933 = 105132
241 + 104891 = 105132

Showing the first eight; more decompositions exist.
