Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013642, here are decompositions:

13 + 1013629 = 1013642
61 + 1013581 = 1013642
73 + 1013569 = 1013642
79 + 1013563 = 1013642
109 + 1013533 = 1013642
139 + 1013503 = 1013642
211 + 1013431 = 1013642
241 + 1013401 = 1013642

Showing the first eight; more decompositions exist.
