Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743028, here are decompositions:

31 + 8742997 = 8743028
97 + 8742931 = 8743028
109 + 8742919 = 8743028
181 + 8742847 = 8743028
211 + 8742817 = 8743028
241 + 8742787 = 8743028
457 + 8742571 = 8743028
487 + 8742541 = 8743028

Showing the first eight; more decompositions exist.
