Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040140, here are decompositions:

47 + 1040093 = 1040140
71 + 1040069 = 1040140
83 + 1040057 = 1040140
89 + 1040051 = 1040140
191 + 1039949 = 1040140
197 + 1039943 = 1040140
239 + 1039901 = 1040140
317 + 1039823 = 1040140

Showing the first eight; more decompositions exist.
