Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742740, here are decompositions:

67 + 8742673 = 8742740
103 + 8742637 = 8742740
163 + 8742577 = 8742740
199 + 8742541 = 8742740
211 + 8742529 = 8742740
229 + 8742511 = 8742740
241 + 8742499 = 8742740
271 + 8742469 = 8742740

Showing the first eight; more decompositions exist.
