Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147186, here are decompositions:

7 + 147179 = 147186
23 + 147163 = 147186
47 + 147139 = 147186
79 + 147107 = 147186
89 + 147097 = 147186
97 + 147089 = 147186
103 + 147083 = 147186
113 + 147073 = 147186

Showing the first eight; more decompositions exist.
