Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737580, here are decompositions:

3 + 8737577 = 8737580
37 + 8737543 = 8737580
79 + 8737501 = 8737580
97 + 8737483 = 8737580
127 + 8737453 = 8737580
157 + 8737423 = 8737580
223 + 8737357 = 8737580
331 + 8737249 = 8737580

Showing the first eight; more decompositions exist.
