Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742782, here are decompositions:

3 + 8742779 = 8742782
43 + 8742739 = 8742782
109 + 8742673 = 8742782
211 + 8742571 = 8742782
241 + 8742541 = 8742782
271 + 8742511 = 8742782
283 + 8742499 = 8742782
313 + 8742469 = 8742782

Showing the first eight; more decompositions exist.
