Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47136, here are decompositions:

7 + 47129 = 47136
13 + 47123 = 47136
17 + 47119 = 47136
43 + 47093 = 47136
79 + 47057 = 47136
139 + 46997 = 47136
179 + 46957 = 47136
269 + 46867 = 47136

Showing the first eight; more decompositions exist.
