Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019642, here are decompositions:

3 + 1019639 = 1019642
79 + 1019563 = 1019642
109 + 1019533 = 1019642
139 + 1019503 = 1019642
163 + 1019479 = 1019642
193 + 1019449 = 1019642
199 + 1019443 = 1019642
229 + 1019413 = 1019642

Showing the first eight; more decompositions exist.
