Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671500, here are decompositions:
- 29 + 8671471 = 8671500
- 31 + 8671469 = 8671500
- 37 + 8671463 = 8671500
- 43 + 8671457 = 8671500
- 53 + 8671447 = 8671500
- 59 + 8671441 = 8671500
- 73 + 8671427 = 8671500
- 107 + 8671393 = 8671500
Showing the first eight; more decompositions exist.
