Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1035640, here are decompositions:

3 + 1035637 = 1035640
41 + 1035599 = 1035640
59 + 1035581 = 1035640
107 + 1035533 = 1035640
113 + 1035527 = 1035640
167 + 1035473 = 1035640
173 + 1035467 = 1035640
191 + 1035449 = 1035640

Showing the first eight; more decompositions exist.
