Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050642, here are decompositions:

11 + 1050631 = 1050642
31 + 1050611 = 1050642
79 + 1050563 = 1050642
139 + 1050503 = 1050642
191 + 1050451 = 1050642
193 + 1050449 = 1050642
211 + 1050431 = 1050642
251 + 1050391 = 1050642

Showing the first eight; more decompositions exist.
