Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737040, here are decompositions:
- 19 + 8737021 = 8737040
- 97 + 8736943 = 8737040
- 157 + 8736883 = 8737040
- 223 + 8736817 = 8737040
- 241 + 8736799 = 8737040
- 313 + 8736727 = 8737040
- 337 + 8736703 = 8737040
- 373 + 8736667 = 8737040
Showing the first eight; more decompositions exist.
