Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040260, here are decompositions:

41 + 1040219 = 1040260
71 + 1040189 = 1040260
101 + 1040159 = 1040260
107 + 1040153 = 1040260
167 + 1040093 = 1040260
191 + 1040069 = 1040260
239 + 1040021 = 1040260
281 + 1039979 = 1040260

Showing the first eight; more decompositions exist.
