Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675740, here are decompositions:

41 + 8675699 = 8675740
89 + 8675651 = 8675740
149 + 8675591 = 8675740
167 + 8675573 = 8675740
383 + 8675357 = 8675740
431 + 8675309 = 8675740
443 + 8675297 = 8675740
641 + 8675099 = 8675740

Showing the first eight; more decompositions exist.
