Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743580, here are decompositions:

19 + 8743561 = 8743580
31 + 8743549 = 8743580
67 + 8743513 = 8743580
127 + 8743453 = 8743580
163 + 8743417 = 8743580
271 + 8743309 = 8743580
367 + 8743213 = 8743580
607 + 8742973 = 8743580

Showing the first eight; more decompositions exist.
