Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719940, here are decompositions:

37 + 8719903 = 8719940
67 + 8719873 = 8719940
109 + 8719831 = 8719940
127 + 8719813 = 8719940
139 + 8719801 = 8719940
193 + 8719747 = 8719940
241 + 8719699 = 8719940
277 + 8719663 = 8719940

Showing the first eight; more decompositions exist.
