Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742692, here are decompositions:

3 + 8742689 = 8742692
19 + 8742673 = 8742692
151 + 8742541 = 8742692
163 + 8742529 = 8742692
181 + 8742511 = 8742692
193 + 8742499 = 8742692
199 + 8742493 = 8742692
223 + 8742469 = 8742692

Showing the first eight; more decompositions exist.
