Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740186, here are decompositions:

3 + 8740183 = 8740186
17 + 8740169 = 8740186
23 + 8740163 = 8740186
29 + 8740157 = 8740186
47 + 8740139 = 8740186
89 + 8740097 = 8740186
149 + 8740037 = 8740186
233 + 8739953 = 8740186

Showing the first eight; more decompositions exist.
