Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737638, here are decompositions:
- 11 + 8737627 = 8737638
- 47 + 8737591 = 8737638
- 61 + 8737577 = 8737638
- 67 + 8737571 = 8737638
- 109 + 8737529 = 8737638
- 137 + 8737501 = 8737638
- 149 + 8737489 = 8737638
- 157 + 8737481 = 8737638
Showing the first eight; more decompositions exist.
