Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102740, here are decompositions:

61 + 102679 = 102740
67 + 102673 = 102740
73 + 102667 = 102740
97 + 102643 = 102740
181 + 102559 = 102740
193 + 102547 = 102740
241 + 102499 = 102740
307 + 102433 = 102740

Showing the first eight; more decompositions exist.
