Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742734, here are decompositions:

61 + 8742673 = 8742734
97 + 8742637 = 8742734
157 + 8742577 = 8742734
163 + 8742571 = 8742734
193 + 8742541 = 8742734
223 + 8742511 = 8742734
241 + 8742493 = 8742734
271 + 8742463 = 8742734

Showing the first eight; more decompositions exist.
