Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761740, here are decompositions:

7 + 8761733 = 8761740
19 + 8761721 = 8761740
37 + 8761703 = 8761740
101 + 8761639 = 8761740
107 + 8761633 = 8761740
109 + 8761631 = 8761740
139 + 8761601 = 8761740
193 + 8761547 = 8761740

Showing the first eight; more decompositions exist.
