Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742702, here are decompositions:

13 + 8742689 = 8742702
29 + 8742673 = 8742702
79 + 8742623 = 8742702
131 + 8742571 = 8742702
151 + 8742551 = 8742702
173 + 8742529 = 8742702
191 + 8742511 = 8742702
233 + 8742469 = 8742702

Showing the first eight; more decompositions exist.
