Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721734, here are decompositions:

61 + 8721673 = 8721734
67 + 8721667 = 8721734
103 + 8721631 = 8721734
127 + 8721607 = 8721734
193 + 8721541 = 8721734
223 + 8721511 = 8721734
331 + 8721403 = 8721734
421 + 8721313 = 8721734

Showing the first eight; more decompositions exist.
